本文根据框架-剪力墙协同工作原理,应用结构力学的角变位移方程,导得结点位移、转角的相互关系式。通过逐次渐近的迭代方法,求得结构的变形和内力。本法同样考虑剪切变形、基础转动的影响,而且可以解算层高不同、刚度任意变化或剪力墙不到顶等特殊情况,具有手算和电算兼容特点,程序简短,很容易在袖珍计算机上实现。通过两个算例分析,计算结果精确可靠,与原例按精确计算法所得结果完全一致。
In this paper, according to the principle of frame-shear wall collaborative work, the angular displacement equations of structural mechanics are used to derive the relationship between the displacements and rotation angles of nodes. Through successive asymptotic iteration methods, the structural deformation and internal forces are obtained. This method also considers the effects of shear deformation and basic rotation. It can also solve special conditions such as different heights, arbitrarily varying stiffness, or less than the shear wall. It is hand-computing and computer-compatibility compatible. The program is short and easy to use in pockets. Realized on computer. Through the analysis of two examples, the calculation results are accurate and reliable, exactly the same as the results obtained by the original calculation method.
