摘要
为简化剪力墙结构的计算方法,引入空间坐标变换,以剪力墙双肢问梁的剪力为基本未知量,以相邻切断点间的间距协调为依据,充分考虑空间变形因素对断点位移的影响,建立剪力墙结构的分析模型。针对该计算模型进行了模拟计算,其变形和内力变化规律与有限元结果完全吻合,而模型要简单得多,而且模型简单、原理清晰,计算简捷,提高分析效率,改善计算精度,又可进一步用于复杂箭力墙结构的分析。
A discrete force method is presented in this paper to simplify the computing method of spatial shear wall structures. This method introduces space coordinates translation, takes the shear force of the wall as fundamental unknown quantity, based on the space adjustment of adjacent tangency points, takes sufficient consideration of the effect derived from the factor of space distortion to the breakpoint, construct readjust equation to educe the analytical model of space shear wall structure. Meanwhile, simulated computations have been performed under this model and got the following findings: its distortion and varying regular pattern of internal force is completely tallies with the result of finite element. Compared with other methods, this model has much more advantages for its simplicity in computation, clearance of theories, high efficiency in analysis, improvement in accuracy. What's more, it can be applied in more complicated analysis of shear force wall structure.
