本文推广了Morley和Braestrup等的工作成果,利用塑性力学的流动理论求得均匀加荷、周边固支或部分约束及轴对称钢筋混凝土环板的解,其中包括刚塑性分析和弹塑性分析。证明了由于板中薄膜内力的作用,钢筋混凝土环板的极限承载力得到较大的提高。最后,通过理论分析和试验结果的比较,说明了本文得到的公式的正确性。 In this paper, we extend the work of Morley and Braestrup, and use the flow theory of plastic mechanics to obtain the solution of uniform loading, peripheral fixed or partially constrained and axially symmetric reinforced concrete ring plates, including rigid plastic analysis and elastoplastic analysis. It is proved that the ultimate bearing capacity of the reinforced concrete ring plate is greatly improved due to the internal force of the film in the plate. Finally, through the comparison of theoretical analysis and experimental results, the correctness of the formula obtained in this paper is illustrated.
