型钢混凝土暗梁受力性能试验研究

为研究型钢混凝土暗梁的受弯和受剪性能,分别进行了6个试件的受弯试验和6个试件的受剪试验。试验着重研究了不同型钢截面尺寸、暗梁截面高度和型钢截面类型(蜂窝式型钢和实腹式型钢)对试件破坏形态、受弯承载力、受剪承载力的影响规律。试验结果表明:受弯试验中,所有试件均表现出良好的受弯性能,延性较好,蜂窝式型钢对试件的变形能力和受弯承载能力影响较小。受剪试验中,所有试件的剪切延性良好,但蜂窝式型钢弱化了型钢混凝土暗梁的抗剪能力。在试验结果的基础上,给出了型钢混凝土暗梁的受弯承载力计算公式,并提出了型钢混凝土暗梁的受剪承载力计算公式,计算结果精度较高,可用于该形式下暗梁的受弯和受剪承载力计算。...

Abstract 为研究型钢混凝土暗梁的受弯和受剪性能,分别进行了6个试件的受弯试验和6个试件的受剪试验。试验着重研究了不同型钢截面尺寸、暗梁截面高度和型钢截面类型(蜂窝式型钢和实腹式型钢)对试件破坏形态、受弯承载力、受剪承载力的影响规律。试验结果表明:受弯试验中,所有试件均表现出良好的受弯性能,延性较好,蜂窝式型钢对试件的变形能力和受弯承载能力影响较小。受剪试验中,所有试件的剪切延性良好,但蜂窝式型钢弱化了型钢混凝土暗梁的抗剪能力。在试验结果的基础上,给出了型钢混凝土暗梁的受弯承载力计算公式,并提出了型钢混凝土暗梁的受剪承载力计算公式,计算结果精度较高,可用于该形式下暗梁的受弯和受剪承载力计算。
