【摘要】 利用STAADPRO有限元软件,用反应谱法分析悬吊换流及阀阀厅在地震作用下结构反应。分析表明,在抗震设防烈度小于8度时,悬吊阀体地震作用对主体结构产生的地震力很小,设计时可不考虑;在抗震设防烈度为7度时,若地震加速度为0.15g,则阀体的最大水平位移为213.5mm,相对悬挂点的位移系数为1/70。更多还原

【Abstract】 The seismic characteristics of the suspending valves and the valve hall are analyzed by using the response spectrum method with software STAADPRO. The results show that the impact from the seismic response of suspending valves to the main structure of the valve hall is very small at 8 degree seismic fortification intensity, so it can be ignored in design. In the case of 7 degree seismic fortification intensity the maximum horizontal displacement of the suspending valves due to seismic response could be 213.5 mm if the acceleration of ground is upto 0.15g, and thus relative displacent coefficient of the suspending point is 1/70.更多还原
