钢管再生混凝土短柱偏压性能实验
摘要
Abstract
Based on eccentric compressive tests of 15 different replacement percentage of recycled concrete filled steel tubes short columns, macroscopic characters of deformation, force-longitudinal strain curves, failure modes and failure mechanism are studied in this paper. The test results showed that the replacement percentage of recycled concrete is an important parameter to the mechanical properties of the recycled concrete filled steel tubes short columns. In the same condition, when the replacement percentage of recycled concrete increases, the bearing capacity will decline to 20%; shrinkage ratio will increase and reduce support to steel tubes, local buckling is accelerated and the bearing capacity will decline.关键词
