中文摘要	为研究增大混凝土填筑高度的开口钢箱-混凝土组合转换梁受力性能,采用有限条带法进行正截面承载力分析计算,并利用ANSYS软件进行了3种有限元模型的分析,模拟钢-混凝土界面不产生滑移、钢梁上翼缘及托板处设置剪力连接件、钢梁上翼缘处设置剪力连接件等3种情况。分析表明,增大混凝土填筑高度可以显著提高组合梁承载力、刚度及变形能力,避免发生脆性破坏。3种模型的极限承载力无明显差别,均满足平截面假定,由此提出了适于工程应用的设计方法。; The bending behavior of an open box steel girder-concrete composite beam with concrete in part of the box girder was analyzed by the finite spline method.Three models were compared in ANSYS including no slip at the steel and concrete interface,with connecters at the upper flanges and a steel plate under the concrete in the box girder and with connecters at the upper flanges.The analyses show that this kind of composite beam has higher bending capacity,stiffness,and ductility that avoids brittle failure than normal composite beams.The ANSYS results show that the positions of the shear connectors do not affect the bending capacity of the composite beam so the plane-section assumption is applicable.A design method of this kind of composite beam is presented based on this assumption.
