新型箱形受弯构件直接强度法分析

NEW BOX-SHAPED FLEXURAL MEMBERS DIRECT STRENGTH ANALYSIS

高强新型冷弯箱型组合构件受弯性能进行模拟分析,通过不同截面形式进行一系列数值分析,以最新计算方法—直接强度法进行计算,与实验数据进行对比。研究表明:实验数据与直接强度法计算的理论数据比较接近,由直接强度法计算的截面随高度变化明显,实验得出的在高宽比相同时极限承载力接近相同。

New high-strength cold-formed box composite member flexural performance was simulated,through a series of different forms of numerical analysis section of the latest calculation methods-direct strength calculation method,compared with the experimental data.Studies showed：experimental data and theoretical calculations direct strength method data were relatively close,section strength from direct strength method was evident with height,in the experimental the ultimate capacity was almost the same with the same height-wide ratio.
