摘要:
以北京LG大厦为研究对象,应用通用有限元软件建立计算模型,对该结构进行竖向地震作用下的行波地震反应分析,给出了该结构顶部典型节点的位移和加速度以及双塔楼框架柱位移、层间位移和内力等,并与在一致输入激励下的地震反应进行比较,继而考虑水平和竖向地震同时作用的行波效应对结构地震反应的影响,探讨了这些节点和框架柱的相关物理量在地震行波作用下的变化规律。将双向(水平和竖向)地震作用下的反应与水平地震作用下的反应进行比较,探讨了双向地震作用下竖向地震作用对结构地震反应的贡献。结果表明:行波效应对结构地震反应的改变较大。
Abstract:
The seismic responses of Beijing LG Building based on a calculating model in the general finite element software under vertical uniform excitation and travelling wave excitation were computed. The displacement and acceleration of the typical nodes at the top of the structure as well as the displacement, story displacement and internal force of the frame columns of two-towers were given, and compared with those under the excitation of uniform input. Then, the seismic response analysis of the structure under horizontal and vertical travelling wave excitation were carried out. The change rules of the respective physical variables of those nodes and frame columns under the traveling wave excitation were discussed. The results of horizontal and vertical seismic excitation were compared with those data produced under horizontal seismic excitation to analyze the role of vertical seismic to seismic response. The results show that traveling wave effect makes the seismic responses of the structure a great change.
