摘要
利用虚功原理推导 ,得出了两端简支弯杆的等效刚度 ,并对采用压弯构件的极限荷载理论得出的不同杆件在不同弯曲状态下的极限破坏荷载Pu 的数据进行拟合 。
The equivalent stiffness of curved bar simply supported at both ends is obtained by the principle of virtual work.In addition,the practical formula for the global stability coefficient of curved bar is also derived from fitting the data of limit load P u of different members under different bendings,which come from the limit load theory for compression bending members.
