基于ETABS的结构地震响应
|
摘要
钢筋砼板柱-抗震墙结构和框架-剪力墙结构相比,具有空间划分灵活,易于获得较大使用面积的优点,但在竖向荷载和水平地震作用时,板柱节点附近的不平衡弯矩会使板内出现塑性变形,从而发生冲切破坏。针对这种情况,提出了框架剪力墙-钢管砼板柱结构。利用ETABS对该新型结构和框剪结构进行动力时程分析,得出相应的结论,为工程实践提供参考。
Compared with frame-shear wall structure,reinforced concrete slab-column-shear wall structure has the advantages that the space is flexible to divide,and it is easy to gain larger area,but under the situation of vertical load and horizontal seismic,the imbalance bending moment in the vicinity of slab-column connections will cause plastic deformation and lead to punching damage.Aimed to this situation,a frame-shear wall and concrete-filled steel tubular slab-column structure is put forward.In the earthquake,comparing frame-wall structure with the new structure in dynamical time-history analysis by using ETABS,it comes to the conclusions and provides reference date for the project.
