摘要

提出了一种新型的带空心RC板的复合细楼板系统，其中预制RC板用作结构构件和永久模板，通过引入轻质填料来减少板的重量，从而实现大的空隙。搭接钢筋穿过钢梁的腹板开孔，从而增强了RC板与钢梁之间的相互作用。作为对所提出的楼板系统的初步研究，在四个试件上对新型复合材料细梁的弯曲性能进行了实验研究。试验和有限元分析结果表明，钢筋混凝土板和钢梁之间的充分相互作用。此外，还提出了一种抗弯承载力的计算方法。双轴空心板；不对称钢梁；弯曲能力。

BENDING CAPACITY OF BIAXIAL-HOLLOW RC SLAB WITH ASYMMETRIC STEEL BEAMS

A new composite slim floor system with voided RC slab is proposed, where the precast RC slab is used as the structural component as well as the permanent formwork, with the large voids achieved by light-weight fillers introduced to reduce the slab weight. The overlapping rebars pass through the web openings of steel beam, thus enhancing the interaction between the RC slab and steel beam. As a pilot study of the proposed floor system, the bending behavior of the new composite slim beam was investigated experimentally on four specimens. The full interaction between the RC slab and steel beam is demonstrated by the test and finite element analysis results. In addition, a calculation method for bending capacity is proposed. Biaxial-hollow slab; Asymmetric steel beam; Bending capacity.
