| 摘 要： | 利用有限元方法对带悬挂阀的阀厅结构进行地震响应弹塑性分析,研究不同场地土条件、不同地震动作用对阀厅结构以及悬吊设备地震响应的影响.研究结果表明:阀厅结构在纵向和三向地震作用下存在较明显的扭转效应；三向地震输入时,吊杆产生的拉力约为单向输入的2倍；悬吊设备竖向地震响应大于水平地震响应,大震下悬吊设备竖向加速度约为水平向的... |

| Abstract: | Elasto-plastic analysis of seismic responses of valve hall structures are carried out using finite element software,and the effects of soil site conditions and seismic ground motion on the seismic responses of the valve hall structures and suspended equipment are studied.Results show that significant torsional responses of the structure can be found under longitudinal and 3D earthquake actions.Under 3D earthquake actions,the seismic responses of the suspended valves are much stronger than those under 1D ear... |
