用于空间剪力墙结构的离散力法

Application of discrete force method in spatial shear walls

为进一步简化剪力墙结构的计算方法,引入空间座标变换,以剪力墙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,建立协调方程,导出针对空间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,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剪力墙结构的分析.

In order to further simplify the computing method of spatial shear wall structures, with space coordinates translation introduced, the shear force of the wall taken as a fundamental unknown quantity, the space adjustment of adjacent tangency points taken as the basis, the effect of space distortion on the breakpoint taken into full consideration readjustment equation has been established and an analytical model has been built for spatial shear wall structures. Simulation computations performed with this model show that the distortion and varying regular pattern of internal force is in good agreement with the results obtained using finite element method: and it can be used for complicated analysis of shear force wall structures.
