Experimental Study On Axial Compressed Reinforced Concrete Column With Steel Plate

Today it is widely applied to engineering reinforce building outside with high-strength material. Especially, it is a safe, reliable, economical and prompt method reinforcing with steel plate.In this article, the author mainly introduced the experimental process and result of axial compressed reinforced concrete short columns with steel plate, in the experiment, 9 short columns specimens were tested including 3 control columns and 3 reinforced ones with Primary loading and 3 reinforced ones with secondary loading. Concrete concentric axial compression property was studied. What's more, the effect for the property of reinforced concrete short columns with primary loading and secondary loading , the stress and strain relation in the strongly and weakly constrain region were discussed emphasis.The article not only made reinforce theory intensive but also provided applied value in the field of reinforce.This article was divided into six chapters. In the first chapter, the author introduce simply reinforce purpose, method, loading character, cause and the current study status at home and aboard. The experimental process design was introduced in the in the second chapter, in the third one, the experimental result was anal sized. The intensive directions were explained with all kinds of figures. In the fourth one, the theory of reinforcing with steel plate was anal sized. Further, the analysis method and steps and design method of bearing capacity were proposed. The theories value was compared with the experimental ones. Obviously, the latter is closed to the former. In the fifth one, the author further studied theories and experimental results with FEA software ANSYS. And come up some good conclusions. In the sixth ones, the above chapters were generalized, notice items were proposed. And the prospect of reinforce technology was expected.
