钢结构住宅开孔组合扁梁楼盖的研究

楼盖体系是影响钢结构住宅性能和造价的重要因素.笔者介绍了目前适用于钢结构住宅中的楼盖体系的主要优点,并在此基础上提出了开孔组合扁梁楼盖体系———开孔梁与下承式楼板组合楼盖.采用有限元分析的方法,对其进行了有限元分析,并对梁板共同工作的可行性和节点处的连接情况进行了研究.分析结果表明,开孔梁与下承式楼板的组合结构整体性能良好,适于在钢结构住宅体系中的广泛应用.

Analysis on Composite Slim Beams Floor-System in Steel Structure Housing

Building floor-system is a significant influence on the performance and cost of steel structure housing construction.In this paper,the features of the current residential floor-system have been summarized,and a new type composite slabs,beam-plate floor,is proposed.The finite element method has been primarily applied in order to research its feasibility and connection condition of steel beam and concrete plate.Consequently,the analysis results indicate that the overall performance of the web-opening steel beams and the new composite is good,and it is hereby worthy to be widely applied in the steel structure housing system.
