摘要
预应力组合梁充分利用了高强预应力筋、钢材和混凝土三种材料的力学性能,具有应用范围广、承载力高、使用性能好、抗疲劳性能优良、经济性较好、施工较复杂等特点,目前在国内外得到了越来越多的应用。本文对预应力组合梁在国内外的最新应用进展进行了总结和回顾,并针对存在的问题提出了有关建议。
Due to efficiently utilizing mechanical properties of high-strength tendons, steel and concrete, prestressed steel-concrete composite beams have the characteristics of extensive applications, large load-capacity, good service-ability and fatigue properties, economy, complexity in construction, et al. At present time, prestressed steel-concrete composite beams have been applied more and more. In this paper, newly progress of applications of prestressed steel-concrete composite beams at China and abroad are summarized and reviewed, then some comments of applications and studies are put forward.
