酸雨环境下钢管混凝土柱轴压性能研究
Research on Axial Compression Performance of Concrete-filled Steel Tubular Columns under Acid Rain
摘要
Abstract
By laboratory accelerated corrosion tests and the electrochemical method, this study analyzes influences of concrete strength, slenderness ratio and the acid rain solution pH value on the axial compression performance of concrete-filled steel tubular columns under acid rain corrosion, and then compares with that of uncorroded con⁃crete-filled steel tubular columns. Experimental results show that the decrease of confinement coefficient caused by steel tube corrosion leads to the decline of the column bearing capacity and its stiffness, impacting its structural safety. The bearing capacity of concrete-filled steel tubes under acid rain corrosion increases with the increase of internal concrete strength grade but decreases with the increasing slenderness ratio.关键词
