基于拉压杆模型的花瓶桥墩受力分析

根据花瓶桥墩实体有限元分析的应力流分布,建立了花瓶墩拉压杆模型,并结合瓯江大桥花瓶墩承载能力的验算,结果表明,采用拉压杆模型计算花瓶墩内力,计算精度能满足工程要求,此种计算方法可供桥梁设计者参考。

Force Analysis of Vase Pier Based on Strut-and-Tie Models

According vase pier finite element analysis of stress distribution,the vase pier strut-and-tie models is established.Combined with the checking of the bearing capacity of the vase pier of Oujiang Bridge,the results shows that the calculation accuracy can meet the engineering requirements by calcula-ting vase pier force using strut-and-tie models,this method of calculation can provide the reference for the bridge builder.
