摘要
推导了钢-混凝土简支梁在任意荷载作用下梁界面的滑移和变形的理论计算公式。并且把钢-混凝土组合梁在特殊荷载-集中荷载作用下的梁界面滑移和变形的理论值与文献[1]的实验值作了大量的比较,其结果吻合良好。此公式既可反应在任意荷载作用下梁界面的滑移,也可计算滑移时对组合梁变形挠度的影响。
It is derived that the theoretical calculating formula of interface slips and deformation of the steal-concrete composite beams. Othermore, the theoretical value are compared with experimental value by them who experiments the interface slips distribution law of deformation If the simply supported steal - concrete composite beams under concentrated loads , the results are very good . the formula can not only describe the interface slips distribution law under freewill loads, but also can take account of its effect on deformations of composite beams.
