自复位钢框架结构中楼板刚度的影响研究

Research on the Influence of Floor Stiffness in Self-centering Steel-frame Structure

通过ANSYS有限元分析软件针对自复位钢框架结构有无楼板的受力性能进行分析研究,经过分析,在单向集中荷载或对称反向集中荷载下的作用下,楼板对自复位梁柱节点约束性能良好,提高了整体结构的抗震性能,很大程度上减小了框架的扩展性.

The stress performance of steel-frame structure with and without floor is analyzed by ANSYS finite element analyzing software.Under the action of the one-way concentrated load or symmetry-reverse concentrated load,the constraint performance of floor on the self-centering beamcolumn joints is good,which can improve the seismic performance of whole structure,largely reducing the framework of extensibility.
