摘要
按经典极限分析理论 ,应用J-UP和J -LOW屈服条件导出逻辑更为协调的上、下限解公式 .而后根据极限状态的原始定义 ,利用有限元法求出极限载荷的精确结果 .在此基础上 ,提出了修正后的四边刚性固定矩形板的极限载荷计算公式 .
According to the classical ultimate analysis theory,the calculation formulas of upper bounds and lower bounds,which are more harmonious in logic,were deduced with the application of J-UP and J-LOW yield conditions .Based on the primal definition of ultimate state and finite element method,more accurate results of ultimate load were obtained.Finally,on the basis of these results,the modified calculation formula of ultimate load of clamped rectangular plates was put forward.
