摘要
介绍了包括方钢管混凝土短柱、方钢管短柱以及素混凝土短柱在内共 １４个试件的轴心受压试验结果，研究了方钢管混凝土短柱的破坏机理、延性和极限承载力，讨论了影响方钢管混凝土轴压短柱性能的主要因素，包括钢管的宽厚比、混凝土的强度等级等。
Experimental results of 14 speciments including concrete-filled rectangular tubular (CFRT) short columns, steel tubular short columns and plain concrete short columns are presented. Based on the test results, the failure mechanism, ductility and ultimate capacity of CFRT short columns are investigated. The effects of the main factors such as D/t ratio and concrete strength on the behavior of concrete-filled square steel tubular short columns are discussed as well.
