摘　　要：在对８根高配筋率的外包钢高强混凝土小偏压短柱试验基础上，进行了角钢与混凝土整体共同工作情况、外包钢小偏压短柱的破坏形态、曲率和挠度分布规律、角钢与受压区混凝土的受力性能、承载力计算、提高配筋率与配箍率及采用高强混凝土对小偏压柱受力性能的影响等多方面的分析研究．还对高配筋外包钢高强混凝土小偏压柱进行了全过程分析．并进一步得出了承载能力直接计算法的简易公式．On the basis of the experiment of eight encased steel-concrete columns with highsteel ratio and high strength concrete under small eccentrical load, this paper discusses thefollowing problems: coordinate work of the angle steel and the concrete; the failure state ofthe encased steel-concrete columns;mechanical properties of the angle steel; distribution lawof the curvature and the deflection; the loaded behaviour of concrete in compressive zone;the calculation of the ultimate capacity and the influnce on the behaviour of smallereccentrical columns in condition of increasing steel ratio and steeks and using high strengthconcrete, etc. The whole work process of this kind of encased steel-concrete colums isanalysed. On the basis of calculation of the column capacity, a simple and practical formulais obtained.
