加设边梁或支撑的板柱结构反应谱分析

Response spectrum analysis of plate column structure with edge beam and support

运用ABAQUS有限元软件对普通板柱结构、加设边梁的板柱结构、加设钢支撑和边梁的板柱结构和加设钢支撑的板柱结构四种结构进行了建模,并通过反应谱分析得到四种板柱结构模型在地震作用下的频率、楼层位移和层间位移,对其进行分析研究。研究结果表明:板柱结构加设边梁或钢支撑后能够更好地改善上部结构的动力特性,可以明显降低地震作用下结构的反应。

Ordinary slab column structure,a side beam slab column structure,a slab column structure steel brace and edge beam and adding steel support plate column structure of four kinds of structures were modeling by using ABAQUS finite element software. The frequency,floor displacement and inter story displacement under the response spectrum were obtained and the analysis of them was carried on. The results of the study shows that,the slab column structure with the boundary beam and steel support can better improve the dynamic characteristics of the upper structure, and can significantly reduce the response of structures under earthquake action.
