【摘要】 提出了在底部剪力法计算柔性连接多、高层钢框架结构的基本自振周期时 ,应考虑节点柔性对它的影响 ,该方法也可同时考虑梁柱效应的影响。通过分析和算例表明 ,考虑节点柔性对钢框架基本自振周期的影响是必要的 ,这样不会使设计过于保守 ,与多、高层钢框架结构实际的受力和变形特点相一致 ,供钢框架设计时参考。更多还原

【Abstract】 The approximate calculation method of fundamental natural period of vibration of multistorey and high rise steel frame structure with flexible connections,in which the flexible connection of joint of beam column and beam column effect (P-δ effect) are taken into account,is presented The calculation results show that it is essential to consider flexible connection of joint of beam column in calculating fundamental natural period of vibration for the steel frame structure with flexible connections using the equivalent base shear method,which corresponds with the practical behavior of stressing and deformation of multistorey and high rise steel frame structure with flexible connections It will be a reference for the design of the steel frame structure更多还原
