【摘要】 根据框架-支撑结构的受力特点,将其分解成纯框架体系和纯支撑体系,这两部分相互协同工作。分别从纯框架体系和纯支撑体系的层间位移求解方法入手,通过这两部分的变形协调推导得到框架-支撑结构体系在水平荷载作用下的层间位移计算公式。并将此简化求解方法的计算结果与有限元法的计算结果进行了对比,结果表明,所用简化算法准确有效,计算步骤清晰明了。更多还原

【Abstract】 Based on the loading characteristic of braced frame structures,the braced frame structures can be divided into pure frame and pure support system,and the two parts can work collaboratively.The interstorey displacement formula of braced frame structures under horizontal load can be derived by deformation coordination,starting with solution of interstorey displacement with the pure frame system and support system.The comparing analysis of two calculation results between simplified calculation method and finite element method has been carried out.The result shows that the simplified calculation method is exact and valid,and the calculation step is much clear.更多还原
