竖向荷载作用下框架厚筏基础的弯矩计算分析

Calculation and Analysis of Bending Moment of Frame Thick Raft Foundation under Vertical Load

通过有限元计算分析、倒梁法以及连续梁计算分析方法对框架筏板基础的弯矩进行计算研究,说明了倒梁法的适用范围及误差,计算研究了大底盘框架厚筏基础弯矩分布规律,说明了整体弯矩对筏板内力设计的影响,并给出了由于差异沉降对筏板配筋的影响。

Through finite element analysis,inverted beam method and continuous beam method,the bending moment of frame raft foundation is calculated and studied.The application scope and error of inverted beam method are explained.The distribution law of bending moment of thick raft foundation with large chassis frame is calculated and studied.The influence of integral bending moment on raft internal force design is explained and given,then this paper gives the influence of differential settlement on raft reinforcement.
