摘要

摘要: 为了促进钢管-钢骨混凝土组合构件在工程实践中的应用,对配置工字形和十字形两种钢骨之构件的受弯承载力进行了研究,采用极限状态的叠加原理推导了两种截面的抗弯承载力计算公式,并通过与文献的试验结果比较,验证了公式的正确性。为了有利于工程上的应用,从经济角度出发,进行了两种截面形式的抗弯承载力比较,得出在用钢量相同的情况下,工形截面的抗弯能力强,从而给工程设计提供了理论依据。

Abstract: To promote the practicing of steel tube and steel-reinforced concrete composite member in the projects,the flexural bearing capacity of H-shaped section and cross steel section is discussed in this article,and limit balance method is used to calculate its bending capacity.Moreover,the accuracy of the formula has been verified.For benefiting to its application in the projects,setting out from economy,it is compared the flexural bearing capacity between two sections.From this,it has been found out that the H-shaped steel section has strong flexural bearing capacity in the same amount of steel.It's offering a theoretic basis to the design.
