The Theory Calculation and Experimental Analysis of Composite Beam JuHua Huanga, JiuHong Jiangb ,Tao Huangc, HouMin Lid Civil Engineering and Building Academy,Hubei University of Technology ,China,430068 aqsh2011@yahoo.cn,bwdm8518@126.com Keywords: composite Beam, experimental analysis, structure experiment Abstract.
Based on this model, this paper discussed the theory calculation and made the corresponding experimental layout and got some experimental data.Compared the experimental data with the results of theoretical calculation，students can strengthen their perceptual knowledge for composite materials beams,and arouse their Learning enthusiasm and train the ability of solving engineering problems.
In addition, in real life, combination materials are widely used in many places, specially in the construction engineering, such as the composite beams of steel beam combinated with concrete bridge panel are used in the main section of the large bridges .
The purpose is to increase the students’ perceptual knowledge to mechanics performance of composite beam combination material, so that students can combine the knowledge with engineering practice better, and further improve the students’ ability to analyze and solve the engineering problems.
