摘　　要：局部承压是工程结构中一种常见的受力情况 ,为了深入认识方钢管混凝土构件在局部压力作用下的性能 ,进行了 2 8个方钢管混凝土轴压短构件局压承载力的试验研究 ,同时还进行了素混凝土局压和钢管混凝土承载力的对比试验 ,以及测量粘结强度的推出试验 ,基于对试验结果的分析 ,考察各主要因素的影响规律 ,并初步建议了方钢管混凝土局压承载力的计算方法。Local compression is a normal case in civil engineering.In order to have a further research on the local compression behaviors of concrete-filled steel tubular members with square sections,28 axially loaded members under local compression were studied.Local compression tests of plain concrete and bearing strength tests of CFST were done simultaneously as a comparison,push-out tests were also carried out for bond strength.Based on the test results,the main factors were studied,and a method for bearing strength calculation was initially proposed.
