摘要
目前,小跨径空心板桥梁中铰缝破坏现象较为严重,极大地影响了桥梁的承载能力和运营安全性。鉴于此,从计算理论出发,借助有限元软件ANSYS对空心板铰缝受力机理进行研究,对传统计算理论提出部分修正,并对计算方法提出了大胆的假定。
Nowadays,the hinged joint destruction phenomenon in short span hollow plank bridge is more serious,which affects the bridge supporting capacity and security operation.In view of this,it embarks from the computation theory,conducts research with the help of finite element software ANSYS to the hinged joint stress mechanism of hollow plank bridge.It puts forward revise to some parts of the traditional computation theory,and proposes the bold hypothesis to the computational method.
