摘要 混凝土含水率影响到混凝土的力学性能,从而对钢筋混凝土结构性能有较大的影响.结合钢筋混凝土短柱单调静力推倒的相关试验,应用SAP2000程序,建立并验证了钢筋混凝土柱有限元分析模型,在不同含水率条件下,对钢筋混凝土柱进行了推倒分析.结果表明:随着含水率的增加,构件基底最大剪力和变形能力呈先提高后降低的趋势,且随着含水率的增大下降幅度越来越大. Moisture content has important influence on reinforced concrete structures.Based on the monotonic static pushover test,the finite element model of the reinforced concrete column is established and verified.The pushover analyses of reinforced concrete columns with different moisture content are carried on by SAP2000.The results showed that,the maximum base shear and deformation capacity of columns rose at first and fell later along with increasing of moisture content,furthermore,decreasing amplitude would increase when moisture content increases.The paper provides a basis of quality evaluation and reconstruction of after-flood concrete structures.
