摘要

    摘要
  • 摘要: 为了研究钢-混凝土双面组合作用梁基本力学性能，设计了2个两跨连续组合梁试件，对其进行静力加载试验，并与有限元模拟结果进行对比。研究结果表明：双面组合作用梁下部混凝土板可分担钢梁压力，其组合作用有利于钢梁下翼缘的稳定性，但对于腹板的稳定性不起作用。组合梁在按照完全抗剪连接进行设计时，可不考虑界面滑移的影响；与普通组合作用梁相比，双面组合作用梁抗弯刚度更大，其负弯矩区长度可延长约28.3%。相同荷载作用下，双面组合作用梁负弯矩值较低，可延缓上部混凝土板的开裂，有效控制混凝土板裂缝宽度和裂缝区范围。下部混凝土板长度按照完全抗剪连接设计的最小长度取值即可，不必过长。ABAQUS有限元模型分析结果与试验结果吻合良好，可较好地模拟组合梁受力性能。提高双面组合作用连续梁下部混凝土板的强度，可有效提高组合梁的承载力和刚度，受力更合理。
    Abstract: To study the mechanical properties of double composite steel-concrete beams, two specimens of two-span continuous composite beams were designed and tested under static load, and compared with the results of finite element simulation. The results showed that the bottom concrete slab of the double composite beam could share the pressure of the steel beam, and its combined action was beneficial to the stability of the bottom flange of the steel beam, but it had no effect on the stability of the web. When the composite beam was designed according to the complete shear connection, the influence of interface slip could be neglected. Compared with the normal composite action, the bending stiffness of double composite beam was larger, and the length of the negative bending moment zone could be extended by about 28.3%. Under the same load, the negative bending moment value of double composite beam was lower, which could delay the cracking of upper concrete slab and effectively control the crack width and crack zone range of concrete slab. The length of bottom concrete slab was in accordance with complete shear resistance, the minimum length of connection design can be established without excessive length. The analysis results of ABAQUS finite element model were in good agreement with the test results, which meant the finite element model in this study can accurately simulate. Improving the strength of the bottom concrete slab of the continuous beam under double composite action can effectively improve the bearing capacity and stiffness of composite beam, and bearing capacity is more reasonable.
