弹性板在结构地震内力计算中的影响分析

Analysis of influence about the calculation of seismic internal force based on elastic plate

采用YJK软件,分别用刚性板和弹性板模拟楼板,计算结构的地震内力,分析柱节点核芯区剪力和梁端弯矩。研究表明:采用弹性板计算的地震内力结果小于采用刚性板计算的结果,提出楼板单元选取的建议。

Seismic internal force of the structure were calculated based on the rigid plate and the elastic plate by using YJK software,both the shear force of the core zone and the bending moment of the beam was analyzed.Research shows that all the results of seismic internal force based on the elastic plate are much smaller than that based on the rigid plate.Suggestions are offered when choosing the element of the slab.
