整浇简支T梁横向分布系数计算方法优选

Optimization of Calculation Method for Transverse Distribution Coefficient of Simply Supported T Beam

如何选择横向分布系数计算方法对桥梁承载力准确性有很大影响.以某公路简支T桥梁为例,分别用刚性横梁法、铰接板法、杠杆法计算某桥各梁的横向分布系数,得出各方法计算的荷载横向分布曲线,并用Ansys建立实体模型,计算模拟的横向分布系数,得出荷载横向分布曲线,并求出各方法相对于实际横向分布系数的残差与残差平方和,最后对比优选出该桥最准确横向分布系数计算方法.

How to choose the transverse distribution coefficient method has great influence on the accuracy of bridge bearing capacity.Taking a highway simply supported T bridge as an example,the transverse distribution coefficients of each beam of a bridge are calculated by rigid beam method,articulated plate method and lever method respectively,and the load transverse distribution curves calculated by each method are obtained.The solid model is established by ansys,the actual transverse distribution coefficients are calculated,and the actual load transverse distribution curves are obtained.Finally,the most accurate method for calculating the lateral distribution coefficients of the bridge is selected by comparison.
