框支墙梁是底层大开间框剪组合墙房屋中的关键构件 ,结合拟动力试验对其进行的静力和抗震性能研究表明 ,房屋的纵、横向托梁均与其上墙体形成墙梁结构 ,并共同形成受力复杂的空间结构体系 ,从而使纵向框支墙梁承担的荷载明显减少。在水平地震作用下 ,纵向框支墙梁承担的荷载较静载情况虽有明显增加 ,但其墙梁结构的受力机理没有发生改变。同时 ,通过空间有限元分析 ,给出了纵向托梁承担荷载的比例 The frame-supported beam is the key component in the frame-shear wall with a large open-space, and the static and anti-seismic performance of the frame-shear wall combined with the pseudo-dynamic test shows that both the vertical and horizontal joists of the building form a wall beam structure with the upper wall , And together form a complex force space structure system, so that the longitudinal frame beam load bearing significantly reduced. Under the action of horizontal earthquake, the load exerted by the longitudinal box beam is much more than that of the static load, but the stress mechanism of the beam has not changed. At the same time, through the finite element analysis of space, the proportion of the vertical load-bearing beam is given
