钢-混凝土组合连梁研究现状及其发展

Research status and development of the steel-concrete composite coupling beam

针对目前我国在钢-混凝土组合连梁的研究工作较少,相关理论很不完善,我国现行的有关规范缺少专门针对钢-混凝土组合连梁的设计计算方法和构造措施的现状,对国内外有关钢-混凝土组合连梁的试验研究、承载力计算以及受力性能影响因素进行了综述和分析评价,对比了几种典型连梁的抗震性能,并指出目前有关钢-混凝土组合连梁研究领域中存在的问题和尚未涉及的方面,为钢-混凝土组合连梁的进一步试验研究及设计提供借鉴和参考。

There is few research on the steel-concrete composite coupling beam in China and the related theory is deficient. There is a lack of specific calculation method and detail measures in the current related codes as well. The steel-concrete composite coupling beam research at home and abroad including experimental study, bearing capacity calculation and influence factors of mechanical behavior were reviewed and evaluated. Seismic performances of several typical coupling beams were compared and the existing problems in the research were pointed out as well as the research field that had not yet been covered. It can provide reference for further experimental study and design on the steel-concrete composite coupling beam.
