Factors Affecting the Structural Behavior of FRP Wrapped Concrete Columns and Applications in Design
Civil and Environmental Engineering, Zhejiang University/University of Illinois at Urbana-Champaign Institute, Haining, Zhejiang, 314400, China
In this paper, the FRP wrapped concrete column is investigated. . According to the research results of Shan et al. (2020) , Li et al. (2006) , and Deb et al. (2010) , this paper analyzes the variables that need to be controlled in the design of columns from these three perspectives: the shape of the cross-section, fiber orientation and bonding between the concrete column and FRP confinement. Impact tests and compressive tests are performed on different specimen. The setting of different samples follows the principle of controlling variables. The results indicate that FRP-wrapped columns with a circular cross-section are better than that with square or rectangular columns and basalt FRP is the optimal FRP material for strengthening the concrete column under the impact. Fiber orientation and types of bonding layers have a great impact on the mechanical properties of FRP wrapped concrete columns.
