摘要
以某高耸进水塔为例,采用ADINA结构分析软件建立了结构-水体动力耦合的三维非线性有限元模型,利用汶川地震中某坝顶处所测得的地震波进行相应的修正处理,作为模型结构的地震动输入,研究了进水塔在正常蓄水位组合地震荷载工况下的地震反应,并分析了其抗震安全性。结果表明,高耸进水塔在实测地震波作用下局部出现损伤开裂,但整体结构仍能确保抗震安全性。
Taking a high-rise intake tower for an example,3D nonlinear finite element model of structure-water body coupling interaction is established by using software ADINA.The monitored seismic wave of dam crest in Wenchuan earthquake is modified and taken as input of the model.And then the seismic response of intake tower and its aseismic safety are analyzed under the conditions of seismic load in normal water level.The results show that the high-rise intake tower appears local damage-cracking under the action of monitored seismic wave,but the whole structure can ensure aseismic safety.
