摘要:
型钢混凝土(SRC)暗梁在大跨度组合楼盖中具有广泛应用前景,结合6个型钢混凝土暗梁试件的单调静力试验,对型钢混凝土暗梁的受弯破坏形态、承载能力和受弯刚度进行了研究.试验着重研究了暗梁截面高度、型钢截面尺寸、型钢截面类型等关键参数对型钢混凝土暗梁的承载能力、受弯刚度的影响规律及影响特点.试验研究结果表明,所提出的型钢混凝土暗梁具有良好的受力性能,进一步结合型钢混凝土暗梁受力机理的理论分析,分别采用“刚心法”和“换算截面法”建立了型钢混凝土暗梁的受弯刚度计算公式,并基于现有规程和理论,提出了型钢混凝土暗梁的正截面受弯承载能力计算方法.
Abstract:
Steel reinforced concrete (SRC) shallow beam in slim floors has a wide application prospect in long-span composite floors. Combined with monotonous static test for six steel reinforced concrete shallow beam specimens, SRC shallow beam flexural failure patterns, its bearing capacity and the flexural stiffness are studied. Experimental research on the shallow beam section height, the size of the steel section, steel cross section type and other key parameters that influence the law and characteristics of the carrying capacity as well as the bending stiffness of the SRC shallow beam. Results show that the proposed SRC shallow beam in slim floors gives good bending performance. Based on SRC beam stress mechanism of theoretical analysis, the ’stiffness-center method’ and ’transformed-section method’ are adopted to an SRC shallow beam flexural stiffness calculation formula. In accordance with the existing codes and theory, and the normal section bending capacity calculation method of the steel reinforced concrete shallow beam in slim floors is put forward
