对中高层弯剪型-弯曲型双重抗侧力结构体系的水平位移计算方法进行了研究.将弯曲型子结构视为仅发生弯曲变形的悬臂墙,将弯剪型子结构视为同时发生弯曲变形和剪切变形的Timoshenko悬臂墙,在此基础上建立了弯剪型-弯曲型双重抗侧力结构体系的位移微分方程,结合边界条件,推导了均布荷载等三种荷载下结构的弯曲变形、剪切变形和总水平位移的解析解.探讨了弯剪型-弯曲型双重结构与剪切形-弯曲形双重结构位移计算方法的关系.结果表明,剪切形-弯曲形双重结构可视为弯剪型-弯曲型双重结构在弯剪型子结构抗弯刚度取无穷大时的一种特殊表现形式.
The calculation method of the horizontal displacement of the middle-high-rise bending-bending type double anti-side-force structure system is studied.The curved sub-structure is regarded as the cantilever wall which only has the bending deformation and the bending-shear sub-structure is regarded as the simultaneous bending Deformation and shear deformation of the Timoshenko cantilever wall, on the basis of which the differential equations of motion of the bending-scissoring-bending double anti-lateral force structure system are established. By combining the boundary conditions, the bending of the structure under uniform loads Deformation, Shear Deformation and Analytical Solution of Total Horizontal Displacement. The relationship between the shear-bending-double structure and the shear-bending double structure displacement calculation method is discussed. The results show that the shear-curve double structure Considered as a special form of the bending-bending-bending double structure when the bending moment of the bending-shear sub-structure is infinitely large.
