| 摘 要： | 为了解倒T形预应力预制构件叠合梁的受弯性能及破坏特征,设计制作了2根叠合梁和1根整浇对比梁,分别进行静载试验,观测叠合梁和整浇梁的正截面开裂荷载、承载力极限荷载、挠度变形、裂缝开展、破坏特征等,并将叠合梁和整浇梁的受弯性能作了比较分析,配筋适当的预应力混凝土叠合梁与对比整浇梁的整体破坏特征基本相同.图8,表4,参4.

| Abstract: | In order to find out bending behavior and destroy properties of composite beam with invertible T-shaped prestressed precast beam,two composite beams and one integral casting beam were designed and manufactured. By experimenting upon these beams, their normal section craze load, bearing capacity load and flexibility were measured respectively, and their crack development and destroy properties were observed.8figs. ,4tabs., 4refs. |
