高性能混凝土钢管柱的试验研究

目前,高性能混凝土逐渐引起了结构工程师和研究人员的兴趣。作为高性能混凝土,自加固混凝土(SCC)具有高流动性,可以不借助机械振动而填充入构件。SCC的特性让这种材料变得极具经济价值,并且在施工及工程方面都具有优势。本文旨在研究薄壁钢管中填充这种高强度混凝土的可能性。对28根填充高性能混凝土的薄壁柱进行试验,主要参数有:1)截面类型:圆形或者方形;2)长细比:12~120;3)荷载偏心率比:0~0·6。计算结果与基于AISC,EC4和DBJ13-51-2003规范设计的柱强度相对比。

Experimental Behaviour of High PerformanceConcrete-Filled Steel Tubular Columns

In recent years, the utilization of high performancconcrete has been the interests of the structural engineersand researchers. As a high performance concrete, self-con-solidating concrete (SCC) is a highly flowable concrete thatcan fill formwork without any mechanical vibration. SCC's u-nique property gives it significant economic, constructabili-ty and engineering advantages. The aim of this paper is thusan attempt to study the possibility of using thin-walled hol-low structural steel (HSS) columns filled ...
