多格式斜桥受力性能分析

Analysis of Skewed Multi-Box Bridges

应用有限条方法分析多格式斜桥，编制了相应的计算程序，进行有机玻璃模型试验，讨论了这种结构受力性能．结果表明，多格式斜桥的受力性能介于板与箱之间，设计计算时可忽略剪力滞的影响，跨中应设置横隔板，而支承端的横向刚度则应相对小些．

The finite strip method is employed for the analysis of skewed multi-box bridges. The organic glass modes were tested, the mechanic characteristics of such structures are discussed, and some suggestions for the design and construction are presented.
