摘　　要：在多层轻钢房屋整体分析时 ,通常不考虑楼盖与钢梁的组合作用 ,偏保守地假设钢结构承受全部荷载 ,这样不仅增加材料用量和结构自重 ,反而会造成强梁弱柱的不利情况。结合北京某小区办公楼的设计讨论了钢 混凝土组合楼盖对多层钢结构设计的影响 ,分析结果表明考虑混凝土与钢梁的组合作用不仅能够降低层高、减少维护结构费用和减轻基础压力 ,而且在提高结构整体刚度方面也很明显。In the design of lightweight steel multi\|story buildings,the floor slab is often taken as dead load without consideration of the composite action between the floor slab and the steel beam;that is,all loads are assumed to be resisted by the steel beams,which results in large consumption of steel.Research on an office building in Beijing shows that the consideration of composite action can reduce not only the structural floor height and maintenance cost of the structure,but also increase the structural stiffness significantly.
