摘要
可靠性指标β的求解是梁板结构可靠度分析中的重点和难点,Matlab计算软件由于其功能强大及简单易懂的突出特点,在β计算中具有明显优势。结合大秦线盖板涵钢筋混凝土盖板实例,分别应用JC法和Matlab优化法,编写Matlab计算程序,对β求解,快速、准确得出计算结果。
In reliability analysis of beam and slab structure,the solution of reliability index β is most important and difficult,and Matlab,one powerful and clear software,has an obvious advantage in calculating β.Combining with the slab culvert reinforced concrete slab of DAQIN railroad,and using JC and Matlab optimization method,the Matlab program is written to solve β rapidly and accurately.
