井格梁板结构的整体塑性极限分析

本文对钢筋混凝土井格梁板结构作了整体塑性极限分析，得出极限承载力的实用计算通式及相应的系数供设计选用．文中引用了梁板同时破坏以及各梁内力间比例符合弹性比例的假定，所得结果比未考虑梁板整体作用塑性分析结果［１］更合理可靠。此外，本文可考虑梁的实际交承情况，解决了按弹性法只能简化为简支或固端之不足，所得结果比弹性结果经济合理，更符合实际受力状况。

Plastic limit analysis of two-way grillage beam and slab structure as a whole

In this paper, Plastic analysis for two-way grillage beam and slab Structure as a whole is presented. By this method, the general formulas and relevant coefficients of the ultimate boring capacity are determined for design. According to the critsrion of the collage of born and slab Structure at the same time and the proPOrtion of each beam internal force identited with elastic one, the acquired result is superior to that of the plastic analysis without the slab effect. Being capable of dealing with the actual beam support, this paper solves the Shortages of turning beam supports only into Simple and fixed end in elastic method. Therefore, the acquired results is more economical and practical than the elastic one.
