大跨径波形钢腹板 PC 箱型刚构桥横向分析

摘要

T he design and analysis of the box bridge in addition to global analysis ,Lateral analysis is also essential .To ensure the transverse safety performance of PC Box‐girder bridge with corrugated steel webs under various load combinations role .In the framework of analysis based on the theory ,respectively ,the security of the roof and floor connections ,the concrete roof and floor w ere tw o aspects of security checking , draw horizontal analysis method .The calculation method will be helpful for the designers in this field .%箱型桥梁设计分析除进行整体分析外，还须进行横向分析。为确保波形钢腹板 PC箱型在各种荷载组合作用下的横向安全性能，以框架分析法为理论基础，分别对顶、底板与腹板连接和顶、底板混凝土两方面的安全性进行验算，得出横向分析方法，该方法对同类桥梁设计有一定的参考价值。
