本文用有限条法对单调横向荷载作用下的钢筋混凝土简支板作了非线性分析。分析中采用二结线低价条。求解释放荷载过狴中引入虚拟刚度概念,用以摸拟拉伸硬化效应。采用等刚度增量迭代法及等刚度迭代法分别给出板的增量解及全量解,并采用了一种加速迭代收敛的方法,本文方法可用到加载至少量钢筋屈服。 In this paper, the finite strip method is used to nonlinearly analyze the simple reinforced concrete slabs under monotonic lateral loads. The analysis uses a low price bar with two lines. The concept of virtual stiffness was introduced into the solution to the release of load to simulate the tensile hardening effect. The equal-stiffenery incremental iterative method and the equal stiffness iterative method are used to give the incremental and all-quantity solutions of the plate, respectively, and an accelerating iterative convergence method is used. This method can be used to load at least the amount of steel yield.
