| 摘 要： | 传统预应力混凝土叠合梁大多采用矩形截面,存在自重大、运输及吊装困难等问题,提出了U形与倒T形两种预应力预制叠合梁.进行了3根U形预应力预制叠合梁、3根倒T形预应力预制叠合梁与1根整浇梁的对比试验,研究其破坏机理、受弯承载力、短期刚度、变形特征及裂缝分布等,并将试验结果与规范计算结果进行了对比.研究结果表明:从开始加载到...

| Abstract: | U-shaped and inversed T-shaped prestressed precast component composite beams(PPCCB) were proposed to overcome the disadvantages of traditional prestressed concrete composite beams such as heavy self weight and the difficulty in transportation and erection due to the use of rectangular cross section.Three U-shaped PPCCB,three invertible T-shaped PPCCB and a cast-in-situ beam were tested.Failure mechanism,flexural capacity,short-term rigidity,deformation behavior and crack distribution were studied.Difference... |
