摘要
本文根据塑性理论中的下限定理,对计算劲性混凝土构件极限承载力的累加方法进行了详细的分析.根据累加方法,利用我国现行混凝土结构设计规范及钢结构设计规范的有关公式给出了劲性混凝土构件正截面受压承载力和斜截面受剪承载力的计算公式.与试验及数值分析结果的比较表明,用累加方法建立的极限承载力计算公式具有相当好的精度.
Based on the lower bound theorem in plastic theory, a method for determining the strength of steel-reinforced concrete (SRC ) member by supposition of separately computed strengths of steel and reinforced concrete members is described in this paper. According to this superposed strength method and by use of the relevant formulas given in the Chinese current design codes for steel and concrete structures respectively, the formulas for calculating the flexural strength and shear strength of SRC members are propo.sedT. he results calculated by the suggested method agree well with those of the tests.
