外包钢高强混凝土小偏压中长柱试验研究

Experiment Study on the Encased Angle Steel high Strength Concrete Median Long Column

在对１０根外包钢高强混凝土小偏压中长柱的试验基础上，进行角钢与混凝土整体共同工作情况、中长柱的破坏形态、角钢与受压区混凝土的受力性能、曲率和挠度分布规律、承载力计算等多方面的分析研究。

On the basis of the experiment the following problems are discussed,including coordinate work of the angle steel and the concrete, the failure state of the encased steel concrete columns, mechanical properties of the angle steel, distribution law of the curvature and the deflection, the loaded behavior of concrete in compressive zone, the calculation of the ultimate capacity, etc. The whole work process of this kind of encased steel concrete column is analyzed.
