Abstract: The limit loads of simply supported circular plate under linearly and uniformly distributed load were analyzed with weighted residual method and Mises yield criterion. Three different trial functions were selected to obtain the analytical solutions of limit loads. The obtained solution is the function of circular plate radius and ultimate bending moment, and it decreases with increasing circular plate radius. The results showed that Tresca criterion forecasts the lower limit of limit load, while TSS criterion forecasts the upper limit of limit load. The limit load forecasted by the weighted residual method just lies between the TSS and Tresca solutions.
