摘　　要：钢-混凝土组合扁梁楼盖不仅能很好地满足房屋建筑方面的要求,显著地降低建筑的层高、围护结构费用和基础压力,且能减少结构的总用钢量,降低结构的单位造价,但当扁梁处于边跨和施工阶段时受较大的偏心荷载,必须考虑扁梁的受扭。组合扁梁楼盖设计和施工时,应注意上述问题并采取抗扭构造措施。Reinforced concrete composite flat beams can not only well meet the requirements in architecture significantly reduce the structural floor height and enclosure expenditures as well as foundation loads but also cut down steel consumption and costs of the structure. However when acting as edge-beams under construction they will bear major eccentric loads and torsion of the beams must be taken into account. Attention should be paid to above-mentioned problems and structural measures taken against the torsion in the design and construction of composite flat beam floors.
