| 中文摘要 | 对一种新型组合梁-钢混凝土组合扁梁的承载力性能进行了试验研究, 共完成3根不同形式的构件: 简支组合扁梁、框架组合扁梁和悬臂组合扁梁。本文还依据组合梁的基本理论对其受力性能做了理论分析, 并与3根试验梁的结果进行了比较。结果表明: 简支组合扁梁, 忽略弹性中和轴以下受拉的混凝土的影响, 采用等效换算截面方法计算所得的刚度和极限承载力与试验结果比较吻合; 悬臂梁只考虑混凝土板中配置的负弯矩钢筋, 忽略混凝土, 计算所得的刚度和极限承载力比试验结果略微偏小, 但相差不大。; In this paper,a new type of slim beams with steel sections encased in a prorietary SP slab were investigated experimentally and theoretically,including a simply-supported beam,a framed beam and a cantilever beam.Good agreement is obtained between the theoretical analysis and the experimental result for simply supported beam:ignoring the concrete in the tension zone,the stiffness and the ultimate capacity by the effective transferred-section method coincide well with the test results.For the cantilever beam,the theoretical stiffness and limited capacity are slightly less than the test ones if considering only the steel beam and the reinforced bars in the negative moment zone with the concrete in the tension zone ignored. |
