摘要
通过对3根不同偏心率的圆钢管混凝土的受压试验,根据组合材料的泊松比,从不同角度分析了此类构件中钢管对核心混凝土的紧箍区域以及偏心率对钢管紧箍作用的影响。初步试验表明,钢管的约束作用,主要取决于组合材料的泊松比大小及发生约束效应的区域大小。
The exprimental study on the 3 short concrete-filled circular steel columns under various eccentrical load is conducted.Base on the poisson ratio of the combination of materials,the confinement effect of steel tube to core concrete and the impact of eccentricity are throughly analyzed in the structure from various angle.The effect of restriction of steel tube depends on the poisson ratio magnitude of the combination of materials and the size class of the effect of restriction.
