本文研究了一种新型的钢-混凝土组合梁，这种组合梁是由预制预应力混凝土桥面板和现浇混凝土板组成的。为了评估这种组合梁的抗弯性能，本研究小组对12个试件进行了试验研究。试验结果表明，在单调荷载作用下，PPCD组合梁具有良好的抗弯性能。根据试验结果，本文还评估了一些关键设计参数（如，混凝土板厚度、剪力钉数量和纵向配筋率）对组合梁抗弯性能的影响。(C)2016爱思唯尔有限公司版权所有
This paper focuses on a new type of steel-concrete composite beams consisting of cast-in-place concrete slabs on Precast Prestressed Concrete Decks (PPCDs). To evaluate flexural performance of such composite beams, this research team conducted an experimental investigation on twelve specimens. Test results show that the composite beams with PPCDs can exhibit desirable and stable flexural performance under monotonic loading. Based upon the test results, this paper also evaluates the influence of some key design parameters (e.g., concrete slab thickness, amount of shear studs and longitudinal reinforcement ratio) on flexural performance of the composite beams.
