| 摘 要： | 通过进行预应力混凝土叠合板受弯性能试验,研究了叠合板抗裂性及裂缝发展规律、挠度、承载力等结构性能。试验结果表明:在标准荷载作用下试件均未开裂,在正常使用状态下的挠度能够满足规范要求。因此,其开裂弯矩、极限承载力、挠度可按《混凝土结构设计规范》(GB50010-2010)进行计算。

| Abstract: | Through flexural performance experimental study of prestressed concrete composite slabs,its structural properties such as anti-cracking,crack development regularity,the amount of deflection and load bearing capacity were researched.The experimental results show：the test slabs didn’t crack under the normal load,the displacement had satisfied the requirement of the code under normal condition.Therefore the ultimate carrying capability,crack and displacement of the slabs can be calculated according to the correlative formula of code for design. |
