摘要
进行了布置筒芯的6m×6m现浇混凝土空心楼盖的试验研究,得到了竖向均布荷载作用下空心楼盖的裂缝发展规律、破坏形态、荷载-挠度关系和极限承载力。结果表明,单向布置筒芯的空心楼盖具有明显的双向受力性质,布置筒芯的现浇混凝土空心楼盖具有良好的变形性能和较高的承载能力。
The 6m × 6m cast-in-situ concrete hollow floor laying tube filler is tested. The development rules of cracks,failure model, load-deformation relationship and ultimate bearing capacity of the cast-in-situ concrete hollow floor bearing vertical uniform load are gained. The results show that the cast-in-situ concrete hollow floor laying tube filler in one way has evident two way character,and it can be provided with good deformation behavior and high bearing capacity.
