锈蚀钢筋混凝土梁的力学性能及拱效应分析
Analysis of Mechanical Properties and Arch Effect of Corroded Reinforced Concrete Beams
摘要
Abstract
Based on the mechanical test of the reinforced concrete (RC)beams with different corrosion ratios of the reinforcement,including 0%,3%,6%,9%,12%,15% and 18%,the indexes of the deflection and the steel strain of the test beams were analyzed with the various loads and corrosion ratios,to investigate the reinforcement stress of the test beams with different corrosion ratio during the load process,and the relation-ship among the arch effect of corroded reinforced concrete beams,the load grade and reinforced corrosion rati-o.The results show that the reinforcement corrosion degrades the bond performance between steel and con-crete;the stress of steel bar transfers from the mid-span to the beam end.In addition,the load-bearing mecha-nism of corroded beam tends to arch effect;the arch effect of corroded reinforced concrete beam enhances with the increase of the load level and the steel bar corrosion ratio.关键词
