摘要
钢管再生混凝土作为一种新型组合结构形式,能够有效改善再生混凝土的固有缺陷。通过外部钢管对内部核心混凝土的约束效应,增强再生混凝土构件的力学性能和防灾效益。现有研究主要从理论分析、试验研究和验证模型入手,对钢管再生混凝土柱的力学性能和变形能力进行探究。基于近年来钢管再生混凝土柱的研究现状进行综述,阐述了钢管再生混凝土柱的力学性能、耐高温性能、耐火性能、抗酸侵蚀性能和抗震性能,并对今后研究方向提出了建议。
Recycled aggregate concrete filled steel tube,as a new combination structure form,can effectively improve the inherent defects of recycled aggregate concrete.The outer casing steel tube exerts a corresponding restraining effect on the internal core concrete.Thereby,enhancing the mechanical properties and disaster prevention effect of the recycled concrete member.Existing research mainly starts through theoretical analysis,experimental research and verification models,and explores the mechanical properties and deformability of steel tube recycled concrete columns.Based on the review of the research status of steel tube recycled concrete columns in recent years,the mechanical properties,high temperature resistance,fire resistance,acid corrosion resistance and seismic performance of steel tube recycled concrete columns were summed up in this paper.Moreover,future research projects were suggested.
