Comparative Study on Dynamic Response of Square Section RC-Members and CFRP-Reinforced Members Under Unequal Transverse Impact Loading
In recent years, fiber-reinforced polymer (FRP) use to enhance existing structural members’ impact resistance has become a research hotspot. This paper investigates Carbon Fiber Reinforced Polymer (CFRP) effectiveness to increase Impact Resistance of Reinforced Concrete Square Member under lateral impact loads. This article clearly said that increased strength of concrete members using CFRP layers leads to increased CFRP layers’ strain. To investigate the effectiveness of Carbon Fiber Reinforced Polymer's use to increase the impact resistance of reinforced concrete square members under lateral impact loads is studied; falling-weight impact tests were conducted. The impact load was applied to the 2L/9 from the length of the RC member's span with a free-falling hammer. All of the specimens with both ends fixed support with short span members were used for these experiments. In this study, the strengthening method and material properties of the CFRP layers and the number of CFRP layers were varied. The results show that using CFRP to strengthen the square RC member specimen in shear effectively prevents shear failure and leads the specimen’s response to be flexural dominated. The short span of the square RC member turns to be shear failure mode dominated by diagonal cracks. The square RC member strengthens with CFRP is shown as bending failure with vertical cracks longitudinal bars rupture. Compared with the square RC member, the impact peak value of the CFRPRC members changes little.
