摘要
对住宅建筑中U型钢-早强混凝土组合梁进行了试验研究,根据实验结果分析其受力、变形特征和破坏机理。分析结果表明:该组合梁承载力高、延性好、刚度大,尤其是其早期强度高,应用在多、高层住宅钢结构工程中,无需模板施工,建设速度快捷,可以发挥其独特的作用.
We carry out experiment and research to U section steel-early-strength concrete beams in residence building, analyze the forcing, deformation characteristic and destruction mechanism. The result shows that it has high bearing capacity, good ductility and large rigidity, especially in early stage. In multistoried and high-rise building with steel structure construction, it has quick speed and no need of form. It may have distinctive effect.
