水平荷载作用下矩形筒仓的内力分析

Internal Stress Analysis for Rectangular Silos Subjected to Lateral Loads

本文对风、地震、单侧装粮等水平荷载作用下的矩形筒仓给出了一种平面展开的计算模式。对这种模式用有限方法进行了应力分析,并给出了相应的计算机程序框图。用本文方法可较精确地算出矩形筒仓仓壁的应力,以便于进行仓壁的强度设计和校验其它近似计算结果的精确程度。

In the paper a computing pattern in stretched plane is given for rectactangular silos subjected to wind and earthquake loading other lateral forces.The pattern is analyzed in stress with finite clement methods, and the computer programme skeleton is correspondingly given. The stress in rectangular silo wall can be accuratly worked out with the method, so as to design the strength of the silo walls and verify the accuracy of the other approximate methods.
