摘要
针对水平荷载作用下带板式柱帽的板柱结构等代框架计算模型中等代梁宽度的取值问题 ,运用有限元分析软件ANSYS6 1对 6组 3 1种不同几何参数的板柱结构进行了水平荷载下的弹性计算 ,研究了等代梁宽度与框架几何尺寸的关系 ,得到了等代梁宽度的计算公式。计算结果与振动台试验结果的对比表明 ,提出的公式具有较高的计算精度。
Thirty-one finite element analysis models of flat-plate structures with slab column-cap with different dimensions are established in order to reveal the relationship between equivalent beam width and the frame dimension.ANSYS6 1 finite element analysis software is carried on in the elastic analysis of structures under lateral load.The relationship between the equivalent beam width and the frame dimensions is studied,and the formula for calculating the equivalent beam width is obtained.The calculated results have been proved with a result of the test of shaking table,which indicates that the formula has the higher precision in calculation.
