According to API 650 E. 7.6, Total design base shear (horizontal force) V , should be equal
to or smaller than the value Vs obtained as follows;
Vs = μ × (Ws + Wr + Wf + Wp + Wns + Wnr ) × (1.0 - 0.4 × Av)
Where,
Vs = Allowable base shear [N]
μ = Maximum friction coefficient for tank sliding
= tan(30°) / 1.5 = 0.3849 for OBE (According to API620 L4.2.10)
= tan(30°) / 1.0 = 0.5773 for SSE (According to API620 L4.3.3)

Wr = Weight of tank roof = 0 [N], Wr = 0.0 [Ton]
Wf = Weight of tank bottom = 821,503 [N], Wf = 83.77 [Ton]
Wp = Weight of liquid content = 5,411,996 [N], Wp = 551.87 [Ton]
Total Weight of Steel and Liquid Content,
Wsum = (Ws+Wr+Wf+Wp+Wns+Wnr)= 278,378 kN, Wsum = 28,473,175 [Ton]
Av(OLE) = Vertical seismic acceleration = 0.2757 [g] for OBE
Av(CLE) = Vertical seismic acceleration = 0.2874 [g] for CLE
Maximum coefficient of friction (API 620 Annex L) μ = tan(30°) / 1.5 = 0.3849 (For OLE)
Maximum coefficient of friction (API 620 Annex L) μ = tan(30°) / 1.0 = 0.577 (For CLE)
Sliding Resistance (Vs)
Vs (OLE) = μ × Wsum × (1.0 - 0.4 x Av), [kN]
= 0.3849 × 279,226 × (1.0 - 0.4 × 0.2757) = 95,622 [kN]
Vs (CLE) = μ × Wsum × (1.0 - 0.4 x Av), [kN]

반응수정계수 행복채움 블로그
반응수정계수 (response modiflcation coefflcient)는 내진설계를 하면서 붕괴방지수준(CLE) 에 대해 검토시
비탄성거동인 소성영역까지 허용하여 저감된 지진력 으로 구조검토를 하게 됩니다.
탄성은 외부로부터 받은 자극이 제거되면 물체를 원래 형상으로 복원시키려는 성질인 반면,
소성은 외부의 자극이 제거되어도 변형을 그대로 유지하려는 성질입니다.
이런 비선형적 거동을 고려할수 있도록 내진설계시 R 응답수정계수를 적용해 줍니다.
Ve: 만약 구조체가 설계 지진의 지반 운동에 대하여 완전히 탄성 거동을 하게 된다고 가정하였을때 지진력에 대해저항하는힘
V: 선형 탄성영역에서의 밑면전단력
이러한 응답수정계수는 설계시 적용할때 마다 구하기는 한계가 있으므로
기준별로 정리되어있어 필요할경우 편리하게 사용하면 됩니다.
주의하실 점은 부재의 연성으로 비탄성변형으로 인한부재력의 저감은
수평력에 대해서만 적용하며， 수직력은 적용하지 않습니다.

3.5 Intermediate stiffener Calculation ( as per EN 14620-2 SEC. 5.2.1.1.2)
3.5.1) The maximum height of unstiffened side wall (Ls) (equ. 18. 10)
According to “Collapse by instability of thin cylindrical shell under external pressure”
by D. F. Windenburg and C. Trilling. Refer to Guide to STORAGE TANK & EQUIPMENT, Bob Long
The David Taylor model basin Formula is used to decide upon the pitching of the stiffeners on the tank shell.
This is taken from the work of Windenburg and Trilling (Reference 18.4), some of which is based on test work
carried out on behalf of the US Navy as far back as 1929.
3.5.2) The number of stiffeners required to stabilise the shell is given by : (equ. 18. 11)

The David Taylor model basin Formula is used to decide upon the pitching of the stiffeners on the tank shell.
This is taken from the work of Windenburg and Trilling (Reference 18.4), some of which is based on test work
carried out on behalf of the US Navy as far back as 1929.

4.7 Sliding Resistance
According to API 650 E. 7.6, Total design base shear (horizontal force) V , should be equal
to or smaller than the value Vs obtained as follows;
Vs = μ × (Ws + Wr + Wf + Wp + Wns + Wnr ) × (1.0 - 0.4 × Av)
Where,
Vs = Allowable base shear [N]
μ = Maximum friction coefficient for tank sliding
= tan(30°) / 1.5 = 0.3849 for OBE (According to API620 L4.2.10)
= tan(30°) / 1.0 = 0.5773 for SSE (According to API620 L4.3.3)
Ws = Weight of tank Shell Plate = 4,590,493 [N], Ws = 468.1 [Ton]
Wr = Weight of tank roof = 0 [N], Wr = 0.0 [Ton]
Wf = Weight of tank bottom = 821,503 [N], Wf = 83.77 [Ton]
Wp = Weight of liquid content = 5,411,996 [N], Wp = 551.87 [Ton]
Total Weight of Steel and Liquid Content,
Wsum = (Ws+Wr+Wf+Wp+Wns+Wnr)= 278,378 kN, Wsum = 28,473,175 [Ton]
Av(OLE) = Vertical seismic acceleration = 0.2757 [g] for OBE
Av(CLE) = Vertical seismic acceleration = 0.2874 [g] for CLE
Maximum coefficient of friction (API 620 Annex L) μ = tan(30°) / 1.5 = 0.3849 (For OLE)
Maximum coefficient of friction (API 620 Annex L) μ = tan(30°) / 1.0 = 0.577 (For CLE)
Sliding Resistance (Vs)
Vs (OLE) = μ × Wsum × (1.0 - 0.4 x Av), [kN]
= 0.3849 × 279,226 × (1.0 - 0.4 × 0.2757) = 95,622 [kN]
Vs (CLE) = μ × Wsum × (1.0 - 0.4 x Av), [kN]
= 0.577 × 278,378 × (1.0 - 0.4 × 0.2874) = 142,159 [kN]

비탄성거동인 소성영역까지 허용하여 저감된 지진력 으로 구조검토를 하게 됩니다.
탄성은 외부로부터 받은 자극이 제거되면 물체를 원래 형상으로 복원시키려는 성질인 반면,
소성은 외부의 자극이 제거되어도 변형을 그대로 유지하려는 성질입니다.
이런 비선형적 거동을 고려할수 있도록 내진설계시 R 응답수정계수를 적용해 줍니다.
Ve: 만약 구조체가 설계 지진의 지반 운동에 대하여 완전히 탄성 거동을 하게 된다고 가정하였을때 지진력에 대해저항하는힘
V: 선형 탄성영역에서의 밑면전단력
이러한 응답수정계수는 설계시 적용할때 마다 구하기는 한계가 있으므로
기준별로 정리되어있어 필요할경우 편리하게 사용하면 됩니다.
주의하실 점은 부재의 연성으로 비탄성변형으로 인한부재력의 저감은

Vs = μ × (Ws + Wr + Wf + Wp + Wns + Wnr ) × (1.0 - 0.4 × Av)
Where,
Vs = Allowable base shear [N]
μ = Maximum friction coefficient for tank sliding
= tan(30°) / 1.5 = 0.3849 for OBE (According to API620 L4.2.10)

반응수정계수 행복채움 블로그
반응수정계수 (response modiflcation coefflcient)는 내진설계를 하면서 붕괴방지수준(CLE) 에 대해 검토시
비탄성거동인 소성영역까지 허용하여 저감된 지진력 으로 구조검토를 하게 됩니다.
탄성은 외부로부터 받은 자극이 제거되면 물체를 원래 형상으로 복원시키려는 성질인 반면,
소성은 외부의 자극이 제거되어도 변형을 그대로 유지하려는 성질입니다.
이런 비선형적 거동을 고려할수 있도록 내진설계시 R 응답수정계수를 적용해 줍니다.
Ve: 만약 구조체가 설계 지진의 지반 운동에 대하여 완전히 탄성 거동을 하게 된다고 가정하였을때 지진력에 대해저항하는힘
V: 선형 탄성영역에서의 밑면전단력
이러한 응답수정계수는 설계시 적용할때 마다 구하기는 한계가 있으므로
기준별로 정리되어있어 필요할경우 편리하게 사용하면 됩니다.
주의하실 점은 부재의 연성으로 비탄성변형으로 인한부재력의 저감은
수평력에 대해서만 적용하며， 수직력은 적용하지 않습니다.

4.7 Sliding Resistance
According to API 650 E. 7.6, Total design base shear (horizontal force) V , should be equal
to or smaller than the value Vs obtained as follows;
Vs = μ × (Ws + Wr + Wf + Wp + Wns + Wnr ) × (1.0 - 0.4 × Av)
Where,
Vs = Allowable base shear [N]
μ = Maximum friction coefficient for tank sliding
= tan(30°) / 1.5 = 0.3849 for OBE (According to API620 L4.2.10)
= tan(30°) / 1.0 = 0.5773 for SSE (According to API620 L4.3.3)
Ws = Weight of tank Shell Plate = 6,416,883 [N], Ws = 654.34 [Ton]
Wr = Weight of tank roof = 2,433,657 [N], Wr = 248.164 [Ton]
Wf = Weight of tank bottom = 1,005,280 [N], Wf = 102.51 [Ton]
Wp = Weight of liquid content = 9,855,820 [N], Wp = 1005.014 [Ton]
Total Weight of Steel and Liquid Content,
Wsum = (Ws+Wr+Wf+Wp+Wns+Wnr)= 309,438 kN, Wsum = 31,648,804 [Ton]
Av(ALE) = Vertical seismic acceleration = 0.2757 [g] for OBE
Av(CLE) = Vertical seismic acceleration = 0.2874 [g] for CLE
Maximum coefficient of friction (API 620 Annex L) μ = tan(30°) / 1.5 = 0.3849 (For ALE)
Maximum coefficient of friction (API 620 Annex L) μ = tan(30°) / 1.0 = 0.577 (For CLE)
Sliding Resistance (Vs)
Vs (ALE) = μ × Wsum × (1.0 - 0.4 x Av), [kN]
= 0.3849 × 310,369 × (1.0 - 0.4 × 0.2757) = 106,287 [kN]
Vs (CLE) = μ × Wsum × (1.0 - 0.4 x Av), [kN]
= 0.577 × 309,438 × (1.0 - 0.4 × 0.2874) = 158,020 [kN]

반응수정계수 (response modiflcation coefflcient)는 내진설계를 하면서 붕괴방지수준(CLE) 에 대해 검토시
비탄성거동인 소성영역까지 허용하여 저감된 지진력 으로 구조검토를 하게 됩니다.
탄성은 외부로부터 받은 자극이 제거되면 물체를 원래 형상으로 복원시키려는 성질인 반면,
소성은 외부의 자극이 제거되어도 변형을 그대로 유지하려는 성질입니다.
이런 비선형적 거동을 고려할수 있도록 내진설계시 R 응답수정계수를 적용해 줍니다.
Ve: 만약 구조체가 설계 지진의 지반 운동에 대하여 완전히 탄성 거동을 하게 된다고 가정하였을때 지진력에 대해저항하는힘
V: 선형 탄성영역에서의 밑면전단력
이러한 응답수정계수는 설계시 적용할때 마다 구하기는 한계가 있으므로
기준별로 정리되어있어 필요할경우 편리하게 사용하면 됩니다.
주의하실 점은 부재의 연성으로 비탄성변형으로 인한부재력의 저감은
수평력에 대해서만 적용하며， 수직력은 적용하지 않습니다.

Vs = μ × (Ws + Wr + Wf + Wp + Wns + Wnr ) × (1.0 - 0.4 × Av)
Where,
Vs = Allowable base shear [N]
μ = Maximum friction coefficient for tank sliding
= tan(30°) / 1.5 = 0.3849 for OBE (According to API620 L4.2.10)

Maximum coefficient of friction (API 620 Annex L) μ = tan(30°) / 1.0 = 0.577 (For CLE)
Sliding Resistance (Vs)
Vs (OLE) = μ × Wsum × (1.0 - 0.4 x Av), [kN]

반응수정계수 행복채움 블로그
반응수정계수 (response modiflcation coefflcient)는 내진설계를 하면서 붕괴방지수준(CLE) 에 대해 검토시
비탄성거동인 소성영역까지 허용하여 저감된 지진력 으로 구조검토를 하게 됩니다.
탄성은 외부로부터 받은 자극이 제거되면 물체를 원래 형상으로 복원시키려는 성질인 반면,
소성은 외부의 자극이 제거되어도 변형을 그대로 유지하려는 성질입니다.
이런 비선형적 거동을 고려할수 있도록 내진설계시 R 응답수정계수를 적용해 줍니다.
Ve: 만약 구조체가 설계 지진의 지반 운동에 대하여 완전히 탄성 거동을 하게 된다고 가정하였을때 지진력에 대해저항하는힘
V: 선형 탄성영역에서의 밑면전단력
이러한 응답수정계수는 설계시 적용할때 마다 구하기는 한계가 있으므로
기준별로 정리되어있어 필요할경우 편리하게 사용하면 됩니다.
주의하실 점은 부재의 연성으로 비탄성변형으로 인한부재력의 저감은
수평력에 대해서만 적용하며， 수직력은 적용하지 않습니다.

4.7 Sliding Resistance
According to API 650 E. 7.6, Total design base shear (horizontal force) V , should be equal
to or smaller than the value Vs obtained as follows;
Vs = μ × (Ws + Wr + Wf + Wp + Wns + Wnr ) × (1.0 - 0.4 × Av)
Where,
Vs = Allowable base shear [N]
μ = Maximum friction coefficient for tank sliding
= tan(30°) / 1.5 = 0.3849 for OBE (According to API620 L4.2.10)
= tan(30°) / 1.0 = 0.5773 for SSE (According to API620 L4.3.3)
Ws = Weight of tank Shell Plate = 14,834,245 [N], Ws = 1512.672 [Ton]
Wr = Weight of tank roof = 0 [N], Wr = 0.0 [Ton]
Wf = Weight of tank bottom = 2,443,621 [N], Wf = 249.18 [Ton]
Wp = Weight of liquid content = 17,277,866 [N], Wp = 1761.852 [Ton]
Total Weight of Steel and Liquid Content,
Wsum = (Ws+Wr+Wf+Wp+Wns+Wnr)= 644,433 kN, Wsum = 65,713,869 [Ton]
Av(OLE) = Vertical seismic acceleration = 0.2597 [g] for OBE
Av(CLE) = Vertical seismic acceleration = 0.3516 [g] for CLE
Maximum coefficient of friction (API 620 Annex L) μ = tan(30°) / 1.5 = 0.3849 (For OLE)
Maximum coefficient of friction (API 620 Annex L) μ = tan(30°) / 1.0 = 0.577 (For CLE)
Sliding Resistance (Vs)
Vs (OLE) = μ × Wsum × (1.0 - 0.4 x Av), [kN]
= 0.3849 × 644,433 × (1.0 - 0.4 × 0.2597) = 222,276 [kN]
Vs (CLE) = μ × Wsum × (1.0 - 0.4 x Av), [kN]
= 0.577 × 644,433 × (1.0 - 0.4 × 0.3516) = 319,543 [kN]

반응수정계수 (response modiflcation coefflcient)는 내진설계를 하면서 붕괴방지수준(CLE) 에 대해 검토시
비탄성거동인 소성영역까지 허용하여 저감된 지진력 으로 구조검토를 하게 됩니다.
탄성은 외부로부터 받은 자극이 제거되면 물체를 원래 형상으로 복원시키려는 성질인 반면,
소성은 외부의 자극이 제거되어도 변형을 그대로 유지하려는 성질입니다.
이런 비선형적 거동을 고려할수 있도록 내진설계시 R 응답수정계수를 적용해 줍니다.
Ve: 만약 구조체가 설계 지진의 지반 운동에 대하여 완전히 탄성 거동을 하게 된다고 가정하였을때 지진력에 대해저항하는힘
V: 선형 탄성영역에서의 밑면전단력
이러한 응답수정계수는 설계시 적용할때 마다 구하기는 한계가 있으므로
기준별로 정리되어있어 필요할경우 편리하게 사용하면 됩니다.
주의하실 점은 부재의 연성으로 비탄성변형으로 인한부재력의 저감은
수평력에 대해서만 적용하며， 수직력은 적용하지 않습니다.

반응수정계수 행복채움 블로그
반응수정계수 (response modiflcation coefflcient)는 내진설계를 하면서 붕괴방지수준(CLE) 에 대해 검토시
비탄성거동인 소성영역까지 허용하여 저감된 지진력 으로 구조검토를 하게 됩니다.
탄성은 외부로부터 받은 자극이 제거되면 물체를 원래 형상으로 복원시키려는 성질인 반면,
소성은 외부의 자극이 제거되어도 변형을 그대로 유지하려는 성질입니다.
이런 비선형적 거동을 고려할수 있도록 내진설계시 R 응답수정계수를 적용해 줍니다.
Ve: 만약 구조체가 설계 지진의 지반 운동에 대하여 완전히 탄성 거동을 하게 된다고 가정하였을때 지진력에 대해저항하는힘
V: 선형 탄성영역에서의 밑면전단력
이러한 응답수정계수는 설계시 적용할때 마다 구하기는 한계가 있으므로

4.7 Sliding Resistance
According to API 650 E. 7.6, Total design base shear (horizontal force) V , should be equal
to or smaller than the value Vs obtained as follows;
Vs = μ × (Ws + Wr + Wf + Wp + Wns + Wnr ) × (1.0 - 0.4 × Av)
Where,
Vs = Allowable base shear [N]
μ = Maximum friction coefficient for tank sliding
= tan(30°) / 1.5 = 0.3849 for OBE (According to API620 L4.2.10)
= tan(30°) / 1.0 = 0.5773 for SSE (According to API620 L4.3.3)
Ws = Weight of tank Shell Plate = 16,736,892 [N], Ws = 1706.688 [Ton]
Wr = Weight of tank roof = 6,335,753 [N], Wr = 646.067 [Ton]
Wf = Weight of tank bottom = 2,941,603 [N], Wf = 299.96 [Ton]
Wp = Weight of liquid content = 26,014,248 [N], Wp = 2652.715 [Ton]
Total Weight of Steel and Liquid Content,
Wsum = (Ws+Wr+Wf+Wp+Wns+Wnr)= 694,149 kN, Wsum = 66,605,335 [Ton]
Av(ALE) = Vertical seismic acceleration = 0.2597 [g] for OBE
Av(CLE) = Vertical seismic acceleration = 0.3516 [g] for CLE
Maximum coefficient of friction (API 620 Annex L) μ = tan(30°) / 1.5 = 0.3849 (For ALE)
Maximum coefficient of friction (API 620 Annex L) μ = tan(30°) / 1.0 = 0.577 (For CLE)
Sliding Resistance (Vs)
Vs (ALE) = μ × Wsum × (1.0 - 0.4 x Av), [kN]
= 0.3849 × 653,175 × (1.0 - 0.4 × 0.2597) = 225,291 [kN]
Vs (CLE) = μ × Wsum × (1.0 - 0.4 x Av), [kN]
= 0.577 × 694,149 × (1.0 - 0.4 × 0.3516) = 344,194 [kN]

반응수정계수 (response modiflcation coefflcient)는 내진설계를 하면서 붕괴방지수준(CLE) 에 대해 검토시
비탄성거동인 소성영역까지 허용하여 저감된 지진력 으로 구조검토를 하게 됩니다.
탄성은 외부로부터 받은 자극이 제거되면 물체를 원래 형상으로 복원시키려는 성질인 반면,
소성은 외부의 자극이 제거되어도 변형을 그대로 유지하려는 성질입니다.
이런 비선형적 거동을 고려할수 있도록 내진설계시 R 응답수정계수를 적용해 줍니다.
Ve: 만약 구조체가 설계 지진의 지반 운동에 대하여 완전히 탄성 거동을 하게 된다고 가정하였을때 지진력에 대해저항하는힘
V: 선형 탄성영역에서의 밑면전단력
이러한 응답수정계수는 설계시 적용할때 마다 구하기는 한계가 있으므로
기준별로 정리되어있어 필요할경우 편리하게 사용하면 됩니다.
주의하실 점은 부재의 연성으로 비탄성변형으로 인한부재력의 저감은

반응수정계수 행복채움 블로그
반응수정계수 (response modiflcation coefflcient)는 내진설계를 하면서 붕괴방지수준(CLE) 에 대해 검토시
비탄성거동인 소성영역까지 허용하여 저감된 지진력 으로 구조검토를 하게 됩니다.
탄성은 외부로부터 받은 자극이 제거되면 물체를 원래 형상으로 복원시키려는 성질인 반면,
소성은 외부의 자극이 제거되어도 변형을 그대로 유지하려는 성질입니다.
이런 비선형적 거동을 고려할수 있도록 내진설계시 R 응답수정계수를 적용해 줍니다.
Ve: 만약 구조체가 설계 지진의 지반 운동에 대하여 완전히 탄성 거동을 하게 된다고 가정하였을때 지진력에 대해저항하는힘
V: 선형 탄성영역에서의 밑면전단력
이러한 응답수정계수는 설계시 적용할때 마다 구하기는 한계가 있으므로
기준별로 정리되어있어 필요할경우 편리하게 사용하면 됩니다.
주의하실 점은 부재의 연성으로 비탄성변형으로 인한부재력의 저감은
수평력에 대해서만 적용하며， 수직력은 적용하지 않습니다.

4.7 Sliding Resistance
According to API 650 E. 7.6, Total design base shear (horizontal force) V , should be equal
to or smaller than the value Vs obtained as follows;
Vs = μ × (Ws + Wr + Wf + Wp + Wns + Wnr ) × (1.0 - 0.4 × Av)
Where,
Vs = Allowable base shear [N]
μ = Maximum friction coefficient for tank sliding
= tan(30°) / 1.5 = 0.3849 for OBE (According to API620 L4.2.10)
= tan(30°) / 1.0 = 0.5773 for SSE (According to API620 L4.3.3)
Ws = Weight of tank Shell Plate = 4,620,697 [N], Ws = 471.18 [Ton]
Wr = Weight of tank roof = 2,187,148 [N], Wr = 223.027 [Ton]
Wf = Weight of tank bottom = 831,408 [N], Wf = 84.78 [Ton]
Wp = Weight of liquid content = 7,639,253 [N], Wp = 778.987 [Ton]
Total Weight of Steel and Liquid Content,
Wsum = (Ws+Wr+Wf+Wp+Wns+Wnr)= 286,240 kN, Wsum = 778,987 [Ton]
Av(ALE) = Vertical seismic acceleration = 0.2769 [g] for OBE
Av(CLE) = Vertical seismic acceleration = 0.3774 [g] for CLE
Maximum coefficient of friction (API 620 Annex L) μ = tan(30°) / 1.5 = 0.3849 (For ALE)
Maximum coefficient of friction (API 620 Annex L) μ = tan(30°) / 1.0 = 0.577 (For CLE)
Sliding Resistance (Vs)
Vs (ALE) = μ × Wsum × (1.0 - 0.4 x Av), [kN]
= 0.3849 × 7,639 × (1.0 - 0.4 × 0.2769) = 2,615 [kN]
Vs (CLE) = μ × Wsum × (1.0 - 0.4 x Av), [kN]
= 0.577 × 286,240 × (1.0 - 0.4 × 0.3774) = 140,228 [kN]

반응수정계수 (response modiflcation coefflcient)는 내진설계를 하면서 붕괴방지수준(CLE) 에 대해 검토시
비탄성거동인 소성영역까지 허용하여 저감된 지진력 으로 구조검토를 하게 됩니다.
탄성은 외부로부터 받은 자극이 제거되면 물체를 원래 형상으로 복원시키려는 성질인 반면,
소성은 외부의 자극이 제거되어도 변형을 그대로 유지하려는 성질입니다.
이런 비선형적 거동을 고려할수 있도록 내진설계시 R 응답수정계수를 적용해 줍니다.
Ve: 만약 구조체가 설계 지진의 지반 운동에 대하여 완전히 탄성 거동을 하게 된다고 가정하였을때 지진력에 대해저항하는힘
V: 선형 탄성영역에서의 밑면전단력
이러한 응답수정계수는 설계시 적용할때 마다 구하기는 한계가 있으므로
기준별로 정리되어있어 필요할경우 편리하게 사용하면 됩니다.
주의하실 점은 부재의 연성으로 비탄성변형으로 인한부재력의 저감은
수평력에 대해서만 적용하며， 수직력은 적용하지 않습니다.

to or smaller than the value Vs obtained as follows;
Vs = μ × (Ws + Wr + Wf + Wp + Wns + Wnr ) × (1.0 - 0.4 × Av)
Where,
Vs = Allowable base shear [N]
μ = Maximum friction coefficient for tank sliding
= tan(30°) / 1.5 = 0.3849 for OBE (According to API620 L4.2.10)
= tan(30°) / 1.0 = 0.5773 for SSE (According to API620 L4.3.3)
Ws = Weight of tank Shell Plate = 6,061,490 [N], Ws = 618.1 [Ton]
Wr = Weight of tank roof = 3,443,340 [N], Wr = 351.123 [Ton]
Wf = Weight of tank bottom = 878,872 [N], Wf = 89.62 [Ton]
Wp = Weight of liquid content = 10,383,702 [N], Wp = 1058.843 [Ton]
Total Weight of Steel and Liquid Content,
Wsum = (Ws+Wr+Wf+Wp+Wns+Wnr)= 258,850 kN, Wsum = 1,058,843 [Ton]
Av(ALE) = Vertical seismic acceleration = 0.27 [g] for OBE
Av(CLE) = Vertical seismic acceleration = 0.336 [g] for CLE
Maximum coefficient of friction (API 620 Annex L) μ = tan(30°) / 1.5 = 0.3849 (For ALE)
Maximum coefficient of friction (API 620 Annex L) μ = tan(30°) / 1.0 = 0.577 (For CLE)
Sliding Resistance (Vs)
Vs (ALE) = μ × Wsum × (1.0 - 0.4 x Av), [kN]
= 0.3849 × 10,384 × (1.0 - 0.4 × 0.27) = 3,565 [kN]
Vs (CLE) = μ × Wsum × (1.0 - 0.4 x Av), [kN]

반응수정계수 행복채움 블로그
반응수정계수 (response modiflcation coefflcient)는 내진설계를 하면서 붕괴방지수준(CLE) 에 대해 검토시
비탄성거동인 소성영역까지 허용하여 저감된 지진력 으로 구조검토를 하게 됩니다.
탄성은 외부로부터 받은 자극이 제거되면 물체를 원래 형상으로 복원시키려는 성질인 반면,
소성은 외부의 자극이 제거되어도 변형을 그대로 유지하려는 성질입니다.
이런 비선형적 거동을 고려할수 있도록 내진설계시 R 응답수정계수를 적용해 줍니다.
Ve: 만약 구조체가 설계 지진의 지반 운동에 대하여 완전히 탄성 거동을 하게 된다고 가정하였을때 지진력에 대해저항하는힘
V: 선형 탄성영역에서의 밑면전단력
이러한 응답수정계수는 설계시 적용할때 마다 구하기는 한계가 있으므로
기준별로 정리되어있어 필요할경우 편리하게 사용하면 됩니다.
주의하실 점은 부재의 연성으로 비탄성변형으로 인한부재력의 저감은
수평력에 대해서만 적용하며， 수직력은 적용하지 않습니다.

4.7 Sliding Resistance
According to API 650 E. 7.6, Total design base shear (horizontal force) V , should be equal
to or smaller than the value Vs obtained as follows;
Vs = μ × (Ws + Wr + Wf + Wp + Wns + Wnr ) × (1.0 - 0.4 × Av)
Where,
Vs = Allowable base shear [N]
μ = Maximum friction coefficient for tank sliding
= tan(30°) / 1.5 = 0.3849 for OBE (According to API620 L4.2.10)
= tan(30°) / 1.0 = 0.5773 for SSE (According to API620 L4.3.3)
Ws = Weight of tank Shell Plate = 6,061,490 [N], Ws = 618.1 [Ton]
Wr = Weight of tank roof = 3,443,340 [N], Wr = 351.123 [Ton]
Wf = Weight of tank bottom = 878,872 [N], Wf = 89.62 [Ton]
Wp = Weight of liquid content = 10,383,702 [N], Wp = 1058.843 [Ton]
Total Weight of Steel and Liquid Content,
Wsum = (Ws+Wr+Wf+Wp+Wns+Wnr)= 258,850 kN, Wsum = 1,058,843 [Ton]
Av(ALE) = Vertical seismic acceleration = 0.27 [g] for OBE
Av(CLE) = Vertical seismic acceleration = 0.336 [g] for CLE
Maximum coefficient of friction (API 620 Annex L) μ = tan(30°) / 1.5 = 0.3849 (For ALE)
Maximum coefficient of friction (API 620 Annex L) μ = tan(30°) / 1.0 = 0.577 (For CLE)
Sliding Resistance (Vs)
Vs (ALE) = μ × Wsum × (1.0 - 0.4 x Av), [kN]
= 0.3849 × 10,384 × (1.0 - 0.4 × 0.27) = 3,565 [kN]
Vs (CLE) = μ × Wsum × (1.0 - 0.4 x Av), [kN]
= 0.577 × 258,850 × (1.0 - 0.4 × 0.336) = 129,283 [kN]
The following table shows the results.

반응수정계수 (response modiflcation coefflcient)는 내진설계를 하면서 붕괴방지수준(CLE) 에 대해 검토시
비탄성거동인 소성영역까지 허용하여 저감된 지진력 으로 구조검토를 하게 됩니다.
탄성은 외부로부터 받은 자극이 제거되면 물체를 원래 형상으로 복원시키려는 성질인 반면,
소성은 외부의 자극이 제거되어도 변형을 그대로 유지하려는 성질입니다.
이런 비선형적 거동을 고려할수 있도록 내진설계시 R 응답수정계수를 적용해 줍니다.
Ve: 만약 구조체가 설계 지진의 지반 운동에 대하여 완전히 탄성 거동을 하게 된다고 가정하였을때 지진력에 대해저항하는힘
V: 선형 탄성영역에서의 밑면전단력
이러한 응답수정계수는 설계시 적용할때 마다 구하기는 한계가 있으므로
기준별로 정리되어있어 필요할경우 편리하게 사용하면 됩니다.
주의하실 점은 부재의 연성으로 비탄성변형으로 인한부재력의 저감은
수평력에 대해서만 적용하며， 수직력은 적용하지 않습니다.
