偏心距对CFRP布加固钢筋混凝土L形柱力学性能的影响
Effect of eccentricity on mechanical properties of reinforced concrete L-shaped columns strengthened with CFRP cloth
摘要
Abstract
This paper highlights an effort to improve the mechanical properties of reinforced concrete L-shaped columns.The research involves developing the reinforced concrete L-shaped column model strengthened with carbon fiber reinforced polymer ( CFRP) using ABAQUS finite element software; per-forming the load-deflection curve and bearing capacity analysis of L-shaped columns to verify the validity of the model;and simulating and analyzing the mechanical properties of reinforced concrete L-shaped col-umns strengthened with CFRP cloth by designing the model members with different eccentricity.The re-sults demonstrate that under eccentric loading, the concrete near loaded column limb and the concrete far away from the load column limb experience the maximum equivalent stress at the middle and bottom of the column respectively;and an increase in eccentricity is accompanied by a gradual decrease in the ultimate bearing capacity of specimens before and after reinforcement, an increase in the ductility and bearing ca-pacity of reinforced concrete L-shaped columns strengthened with CFRP cloth, and thus a remarkable re-inforcement effect.This study may provide a reference for an insight into L reinforced concrete columns with CFRP reinforcement.关键词
