考虑现浇楼板影响的框架结构抗震性能分析

摘要

为了研究现浇楼板对钢筋混凝土框架结构抗震性能的影响，文章利用 pushover 方法对3个钢筋混凝土框架结构模型进行了分析研究，包括不考虑现浇楼板、考虑现浇楼板以及考虑现浇楼板钢筋影响的空间框架结构。通过对计算结果进行分析比较得出一些结论，并对框架结构抗震设计给出一些建议，提出考虑楼板影响的框架结构抗震设计方法，可供实际框架结构设计时参考。%To study the effect of cast-in-situ floor slab on the seismic performance of reinforced con-crete frame structure,three reinforced concrete frame structure models were analyzed by pushover analysis in this paper,the first with no considering the effect of cast-in-situ floor slab,the second considering the effect of cast-in-situ floor slab,and the third considering the effect of cast-in-situ floor slab steel.Conclusions were obtained by analyzing and comparing the results and frame structure seismic design suggestions were pro-posed.The seismic design method with considering the effect of the cast-in-situ floor slab on frame structure was proposed to be referred in the actual frame structure design.
