钢—混凝土组合梁的抗弯承载力分析

Analysis on the Bend Supporting Force of Steel-concrete Combination Beams

结合某六层钢结构工程实例,引入一种钢—混凝土组合梁的实用计算模型,提出了该受弯构件在使用阶段正截面抗弯承载力计算方法,并以试验为基础进行对比分析。研究表明:该组合梁强屈比大,抗弯承载力高,施工速度快,运用在多层及小高层民用建筑结构中有其独特的优越性。

On the collision between an engineering example of six - floor steel structures and a practical cauculation model of steel -concrete combination beams,flashed,in the stage of the bearing bend member being used, a calculation method of the bend supporting force of its normal cross section. Further a contrastive analysis based on the experiment has made it clear that the combination beam with such characteristics as large ratio of strength -deformation, high bend supporting force and high speed construction,is particularly superior in civil construction structures for multi -layer and high buildings.
