摘要
结合工程实例,介绍了超宽箱梁的设计和分析,基于折面梁格法对超宽箱梁的剪力滞效应进行了全面研究,采用活载影响面加载法对横向多支座的反力进行了计算。
Combined with engineering example, the paper introduced the design and analysis of ultra wide box girder, studied shear lag effect of ultra wide box gird by folding grillage, and calculated the reaction of transverse multi supports by influence surface method.
