摘要
斜腿刚架桥由于桥墩受到压弯作用,结构可能发生失稳。基于对斜腿刚架桥分别进行的线性和非线性稳定性计算,分析该型桥梁的失稳特点,研究了2种计算方法的区别和计算结果差异。计算结果表明,斜腿钢架桥容易发生桥墩横向失稳,对于该桥型的营运,非线性分析结果比线弹性分析结果更安全。
Skew-legs rigid frame bridge will become instability because of the compression-bending pier.based on the linear and nonlinear analysis of Skew-legs rigid frame bridge,The study analyzed the characteristic of stability,and compared the difference of the two methods.The results showed that the pier will become instability on transverse.The answer of nonlinear method is more conserved.
