The assessment of shape configuration effect of CFRP strips on the lateral capacity of shear walls with different aspect ratios

Abstract

ABSTRACTThe purpose of this study is to find the effect of shape configuration of carbon fibre reinforced polymer (CFRP) strips on the lateral capacity of shear walls. For this purpose, a model of shear wall strengthened with different layout configurations of CFRP was investigated by pushover analysis. All carbon fibres placed symmetrically on reinforced concrete (RC) walls, and any sliding effect of fibres on concrete was neglected. Also, the effect of change in the aspect ratio of the RC wall on CFRP strengthening pattern was studied. Throughout the study, the results of all CFRP configurations and the increase in lateral strength were compared. With an increase in the number of fibre layers on all specimens strengthened with CFRP, change in lateral strength and in the shear wall damage occurred. By all specimens’ comparison, the best fibre configuration in each h/L ratio was determined.Abbreviations: CDP: Concrete Damage Plasticity; CFRP: Carbon Fiber Reinforced Polymer; FRP: Fiber Reinforced Polymer; h/L: Height/Length; RC: Reinforced Concrete; 2D: Two Dimensional; 3D: Three Dimensional
