摘要
为了研究钢-高强混凝土组合梁在静载作用下的抗弯性能,本文完成了8根钢-高强混凝土组合梁在跨中两点对称荷载作用下的试验,对其受力性能进行了分析,并探讨了翼缘板混凝土强度、钢梁屈服强度和翼缘板宽度对组合梁正截面受弯承载力、延性的影响。结合试验结果和理论分析,对现行规范中组合梁正截面受弯承载力计算公式进行了补充修正,以拓宽计算公式中翼缘板混凝土强度的适用范围,为高强混凝土在钢-混凝土组合梁中的应用提供设计依据。
The experimental and theoretical analysis of Steel HSC(High Strength Concrete) composite beams under static concentrate lateral loads were presented. Eight tests of Steel HSC composite beams had been performed. The bending capacity of Steel HSC composite beams was studied in this paper. The influences of concrete strength, yield strength of steel beam, width of concrete flange on bending capacity and ductility of Steel HSC composite beams were discussed. Based on the experimental study and theoretical analysis, modification is proposed on the design equations of bending capacity of Steel HSC composite beams in current codes, which expands the scope of application of concrete strength in design formulae and can be provided as the design basis on Steel HSC composite beams.
