铰接板梁法横向分布系数的计算分析

Calculation Analysis on Coefficient for Lateral Distribution by Hinge-jointed Plate Girder Method

常用的荷载横向分布计算方法多是在引入计算假定和简化的基础上推导的,难免和实际结构有一定的偏差.本文采用有限元软件ANSYS,利用空间梁单元对铰接板梁进行分析,得出荷载横向分布,并与手算的横向分布结果进行对比.

The most calculation method of lateral load distrbution coefficient which is commonly used is educed based on introducing caculation assumption and simplification.Comparing with the actual structure,the warp is sure to exist.The software ANSYS is introduced in this paper.The analysis of hinge-jointed plate girder is given by using space beam.Lateral load distribution coefficient is obtained and compared with the theoretic calculating result.
