摘要
Abstract
This article studies the antifreeze durability of recycled concrete filled steel tube (R-CFST) by freeze-thaw tests,and simulates the tests with finite element software. It shows that the loss of elastic modulus of hollow R-CFST is more than that of the solid R CFSTpwhether the concrete is water-saturated affects ihe frost-thaw deformation of hollow R-CFST less than that of solid R-CFSTjthe confining force caused by the change of temperature does not affect the CFST too much. The research of the experiment is pioneering at home and abroad,so the correlative reports have not been found currently.关键词
