摘要
在已建立的钢筋混凝土随机有限元理论的基础上进一步提出了可考虑各基本随机变量的实际概型分布的计算方法,使得可靠指标的计算更为准确;以钢筋混凝土适筋梁为例,导出了钢筋混凝土非线性随机有限元的计算步骤.
Based on the ready - cstablished theory of stochastic finite clement method for reinforced concrete, this paper further presents the formulac of load effect calculation, which arc able to take account of real probability distribution of rcspectivc random and make the calculation of reliability index more accurate. The detailed reliability index calculation method is also derived for the nonlinear SFEM analysis, taking an adequately reinforCed concrete beam for example.
