刚性横梁法在多格式上部结构上的应用

Rigid Transverse Beam Bethod on Analysis of Multi-box Superstructure

本文以多格式上部结构为分析对象,以有机玻璃模型试验结果为依据,分析了这种结构的受力性能。分析结果表明,在内力横向分布计算中,采用刚性横梁法应考虑其整体抗扭刚度的修正。

In this paper,taken the multi-box superstructure as the analysis object,based on the test results of the organic - glass model,the constrvctive characteristic of such structure under loading is analysised. From the analysis result,it can be seen that the rigid transverse beam method must be revised with its whole torsion stiffness in the calculation of the load distrabution of the multi-box superstructure.
