Axial compression tests for brick square columns strengthened with cement-based composites and carbon fiber textile mesh
摘要
Abstract
To address the insufficient load-bearing capacity of existing brick columns,alongside the large spatial occupation and poor synergistic performance of traditional methods,an experimental study was conducted to investigate the applicability and working mechanism of a composite strengthening technology utilizing cement-based composites and carbon fiber textile mesh.Axial compression tests were performed on 18 brick square columns(9 groups)to evaluate the effects of strengthening schemes(unstrengthened,single textile mesh,single cement-based composite,and composite strengthening),mesh layers(1-3),and slenderness ratios(2-4)on the failure modes,load-bearing capacity,and deformation performance of the core columns.Results indicate that the failure of composite-strengthened columns is primarily triggered by transverse tensile mesh fracture caused by stress concentration at the corners.This lead to confinement loss and core crushing,while maintaining effective interfacial bonding.The composite system significantly enhances capacity and ductility,outperforming single mesh and single cement-based strengthening by 104％-113％and.22％-46％,respectively.Increasing mesh layers improve the confinement effect,capacity,and ductility,whereas a higher slenderness ratio significantly reduces load-bearing capacity.Based on four fundamental assumptions,the Richart strength model,and Lam & Teng's confinement theory,a formula for calculating the normal-section axial compressive capacity of composite-strengthened columns was established.The calculated values demonstrate good agreement with experimental results,yielding an average ratio of 0.91.关键词
