摘要

针对水平荷载作用下带边梁的现浇混凝土空心板柱结构等代框架计算模型中等代梁宽度的取值问题,运用有限元分析程序对4组28种不同几何参数的空心板柱结构进行水平荷载作用下的弹性计算分析,研究等代梁宽度与结构几何参数的内在关系,从而得到等代梁有效宽度系数的计算公式以及边梁抗弯刚度的增大系数,为进一步计算提供了依据.
In order to study the equivalent frame calculation modes for hollow slab-column structures of reinforced concrete under lateral load,this paper conducts an elasticity analysis of such structures with edge beams of different dimensions by using a finite element structural program,and establishes their models accordingly.It further analyzes the internal relationship between the effective beam width and the frame dimensions,thus obtaining a formula for calculating the width coefficient of their equivalent frame and the increasing coefficient of edge beams.
