| 摘 要： | 针对多高层钢框架立体车库,推导了车库结构等效抗剪刚度和等效抗弯刚度的计算公式,包括支撑抗剪刚度、框架抗剪刚度和框架抗弯刚度;对车库结构进行了连续化处理,推导了在不同荷载形式作用下结构侧移的计算公式,并与有限元软件ANSYS的分析结果进行了比较.比较结果表明该公式计算误差保持在5%以内,非常精确,而且公式形式简洁,使用方便,为多高层钢框架立体车库的结构选型、构件截面尺寸的确定提供了一个快速有效的初步设计方法.

| Abstract: | Aiming at the multi-story and tall steel tridimensional garage structure,the calculation of equivalent shear stiffness and equivalent bending stiffness of the structure are derived,including shear stiffness of the lateral bracing and frame and bending stiffness of the frame.In a continuous way,the formulas of the structural lateral displacement under different load patterns are developed.It shows that the error of the results by the presented formulas does not exceed 5% in comparison with those by finite element method.Besides,the form of these formulas is briefness.Therefore,the method and formulas are very useful for preliminary design of the steel tridimensional garage. |
