摘要
本文将广义阶梯函数应用于薄板的塑性极限分析问题，用以简化计算简支圆板在复杂荷载作用下的极限荷载。文中针对简支圆板在任意局部均布荷载和线性分布荷载共同作用下的塑性极限分析问题，并考虑荷载的五种不同的分布形式，给出相应的极限荷载的计算公式。
In this paper,generalized step function is app1ied the plastic limit analysis of thin plates,and simplified calculations of limit loads of simply supported circular plates under complicatedloads are carried out.It aims to plastic limit analysis of simply supported circular plates,and thefive possible distribution form on random local uniform and linear load have been considered.Thecorresponding calculating formulas of limit foad have been given out by generalized stepfunction.
