摘要
钢-混凝土组合扁梁是将钢梁内嵌于混凝土之中的新型组合梁,它能最大限度地降低结构的高度,形成类似"无梁楼盖"的结构体系,已在住宅钢结构中推广应用,其承载性能和设计方法研究引起了结构工程界的关注.本文采用通用有限元程序ANSYS研究了组合扁梁的承载力问题,通过建模计算了简支组合扁梁、悬臂组合扁梁和框架组合扁梁的承载力和变形特征,得到了相应的荷载-位移过程曲线,并与组合扁梁的试验结果进行了比较,验证了计算结果的正确性.
Steel-Concrete composite slim beam is a new type of composite beams with steel sections encased in concrete slab. Consequently, the structural height can be reduced similar to a beamless floor system. In this paper, a new type of slim beams fabricated with a propriety SP slab is investigated by finite element method. Three types of beams are analyzed, including a simply-supported beam, a framed beam and a cantilever beam. The stiffness and loading capacity are evaluated and verified with the experimental results. The load-deflection curves are also reported and agree well with the test records.
