Study on BFRP Constrained Preloaded Concrete Square-Shaped Column

Abstract:

It was proceeded to the specimen without load in the former research of FRP constraint concrete. And this was not conformed to the reality of unload of the structure member when reinforcing. So that, this paper carried on the test research of BFRP constraint concrete square column. During the test, the deformation and the load random were recorded. Disposing the data, many stress-strain curves were plotted. Analyzing the curves, it was found that: BFRP can enhance the concrete obviously. At the same time, the effect of axial compression ratio preloaded to reinforcement was analyzed in the paper.
