摘要:
采用有限元软件进行单向、双向罕遇地震作用下框架-核心筒结构弹塑性时程分析，通过单向、双向罕遇地震作用下结构响应对比，分析了双向罕遇地震作用对结构顶点位移、层间位移角、楼层相对扭转角及相对加速度的影响；通过改变地震波输入角度，考察了其对结构响应的影响。结果表明：单向、双向罕遇地震作用下的结构层间位移角曲线较为相似，但是双向罕遇地震作用下的结构层间位移角明显较单向作用下的大；地震动特性对楼层扭转角的影响较为显著，一般相对扭转角最大值均出现在结构的顶层；楼层响应相对加速度最大值一般出现在结构底部1/5~3/5结构高度内或结构的顶部；地震波输入角度对结构响应的影响较大。
Abstract:
Based on the finite element software, elasto-plastic time history analysis of a framecore tube structure under axial or biaxial severe earthquake actions was carried out. By contrasting, the effects on building top displacement, drift, relative torsion angle of floor and the relative acceleration of structure were analyzed. At the same time, the effect of earthquake input angle on the building was studied. The results indicate that the drift curves of structure under axial or biaxial earthquake actions are similar. However, the drifts of structure under biaxial actions are bigger than those under axial actions. The floor torsion angle is affected significantly by the ground motion characteristics. Furthermore, the peak value of floor torsion angle occurs at the top of the building. The peak value of relative acceleration occurs at the 1/5-3/5 structure height or at the top. The building response is influenced obviously by the earthquake input angle.
