【摘要】 考虑杆件远端刚结点处杆件数目、各杆线刚度及梁柱刚度比值的影响,推导出杆端的转动刚度和传递系数统一计算公式。将框架结构竖向荷载作用下的内力计算分成若干个单结点结构计算,这种计算方法对框架结构的梁柱线刚度比没有范围限制,使用范围广,计算工作量少,精度高。更多还原

【Abstract】 Considering the number of members,linear stiffness of every member and beam-column stiffness ratio at distal rigid nodes of member,a unified formula has been derived to calculate rotational stiffness and transmission coefficient of beam end.The frame structure is divided into some single joint structures to compute its internal force under vertical loads.The method proposed in this paper has not any scope limitation of beam-column linear stiffness ratio.This method has the advantages of high accuracy,small computational amount and wide range of use.更多还原
