考虑楼板变形时框支剪力墙结构的框支层合理设计研究
|
摘要
将框支剪力墙结构沿竖向划分成为转换层上部剪力墙结构和转换层下部框架-剪力墙结构。对各部分结构假定质量刚度沿高度均匀分布,将楼板看成水平放置的深梁,并假定以剪切变形为主。根据平衡条件,列出微分方程组。采用相应的数学程序求解,得到结构水平侧移及各构件内力。通过对内力和侧移的双重控制,进行框支层的合理设计。
The shear wall structure supported on frame-shear wall structure was studied in continuous method along vertical height,and the plates were looked upon as horizontal deep beam and at the same time,it was assumed that the shear distortion was the main distortion in plates.Systems of differential equations are obtained by stress balance condition,then the structure horizontal displacement and every element internal force were solved by mathematical program.At last,the rigidity of shear wall linked with the ground was deduced strictly from both controls of resistance to shear force and the maximum ratio of sideway to height of the bottom floor under earthquake actions.The example reveals that structures design will be more reasonable and safer when distortion of plate is considered.
