摘要
为提高现有叠合楼板抗弯性能,满足大跨度结构要求,提出一种新型灌浆钢管桁架混凝土叠合板。通过对两块两端简支的叠合板进行均布荷载试验,研究了叠合板的变形性能、裂缝开展规律、承载力及破坏模态等,并对叠合板的抗弯承载力和变形性能进行了理论分析。试验结果表明:叠合板具有良好的延性,满足施工要求。
In order to improve the flexural behavior of existing composite slabs and meet the requirements of long-span structure,a new type of concrete composite slab with grouted-round-steel tube truss was put forward. Two specimens with simply supported ends were tested under uniform load to investigate the deformation properties,laws of crack development,bearing capacity and failure mode of the slab. The theoretical analysis for the deformation properties and ultimate flexural capacity of the slab were carried out. The experimental results showed that the slab had good ductility,which could meet the requirements of construction.
