【提要】  進行了布置筒芯的6m×6m現(xiàn)澆混凝土空心樓蓋的試驗研究，得到了豎向均布荷載作用下空心樓蓋的裂縫發(fā)展規(guī)律、破壞形態(tài)、荷載-撓度關(guān)系和極限承載力。結(jié)果表明，單向布置筒芯的空心樓蓋具有明顯的雙向受力性質(zhì)，布置筒芯的現(xiàn)澆混凝土空心樓蓋具有良好的變形性能和較高的承載能力。

Experimental Study on Castinsitu Concrete Hollow Floor Laying Tube Filler/Yang Jianjun, Cheng Jieyun, Wang Jin, Yang Chengxi, Tan Juxiang(Civil Architectural Engineering College, Central South University, Changsha 410075, China)
Abstract: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.
Keywords:tube filler；castinsitu concrete hollow floor；experimental study；capacity; deformation
