摘　　要：本文通过对国内外大量的钢筋砼板和基础试验资料的分析,划分了三种不同类型的破坏形态,即弯曲破坏、弯冲破坏及冲切破坏,建议了各类破坏形态的极限承载力计算公式,并提出了判别各种破坏类型的简便方法,计算结果与试验结果符合良好。By analysis of the experimental data available in literature at home and abroad, it can be found that there exist three types of failures in the tests of reinforced concrete slabs and footings, i.e., flexural failure, flexural-punching failure and punching failure. The expression of the ultimate bearing capacity of reinforced concrete slabs and footings derived from the failure types and a simple criterion of failure types are presented in this paper. They all agree well with the results of slabs and footing tests.
