【摘要】 本文导出U型钢-混凝土组合梁在使用阶段正截面受弯承载力的计算,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,受弯承载力高,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。更多还原

【Abstract】 A cauculation method of the bending capacity of normal cross sections in service stage of U section steeland concrete composite beams is deduced in this article.Further a contrast analysis research based on a experiment has made it clear that composite beams have characteristics of large ratio of ultimate bending strength to yield strench,high bending capacity and high construction speed,thus they have particularly superior in civil building structures for multilayer and high buildings.更多还原
