对钢管混凝土轴压短柱的受力性能进行了试验研究。共测试了32个样本。试验中改变的主要参数有：（1）截面型式：圆形和方形;（2）局部受压面积比（混凝土横截面积与局部受压面积之比）：1.44和16;（3）端板厚度：从2到12毫米。有限元分析模型用于分析钢管混凝土短柱受到轴向局部压缩，用该模型计算的结果与试验结果的比较表明，两者基本吻合。然后利用理论模型研究了组合柱轴向局部受压的机理。(c)2007爱思唯尔有限公司保留所有权利。
The behaviour of concrete-filled steel tubular (CFST) stub columns Subjected to axially local compression was experimentally investigated in this paper. A total of thirty-two specimens were tested. The main parameters varied in the tests are: (1) sectional types: circular and square; (2) local compression area ratio (concrete cross-sectional area to local compression area): 1.44 and 16; and (3) thickness of the endplate: from 2 to 12 mm. A finite element analysis modelling was used for the analysis of CFST stub columns Subjected to axially local compression, and a comparison of results calculated using this modelling shows generally good agreement with the test results. The theoretical modelling was then used to investigate the mechanism of the composite columns subjected to axially local compression. (c) 2007 Elsevier Ltd. All rights reserved.
