对常见的剪切刚度、楼层剪力与层间位移比、剪弯刚度三种结构抗侧刚度计算方法展开分析,探究各方法的适用性及优缺点,结果表明,剪切刚度为剪弯刚度简化计算方法,其可应用于结构方案阶段,当1≤h/b≤4时,计算误差较大;按楼层剪力与层间位移的比值计算侧向刚度时,由于存在无害位移影响,其计算结果往往偏小;采用剪弯刚度可以较为精确合理计算结构抗侧刚度,其计算代价也较高。
The calculation methods of common lateral shear stiffness, floor shear and interlayer displacement ratio and bending stiffness were analyzed. The applicability, advantages and disadvantages of each method were discussed. The results show that the shear stiffness is the shear stiffness The calculation method is simplified, which can be applied to the structural scheme stage. When 1≤h / b≤4, the calculation error is large. When the lateral stiffness is calculated according to the ratio of floor shear and interlayer displacement, due to the harmless displacement, The calculation results tend to be small; using shear stiffness can be more accurate and reasonable calculation of structural lateral stiffness, the computational cost is also higher.
