| 摘 要： | 进行了 13块集中荷载作用下四边简支叠合矩形板二次受力的试验 ,对其受力性能作了系统的分析 ,提出了叠合面等剪应力线模型 .试验结果表明 :叠合板的受冲切承载力不低于条件相同的整浇板 ;叠合板中的两期混凝土强度较低的一种混凝土强度对受冲切承载力具有控制性 .建议叠合板的叠合面可采用自然粗糙面 ,且叠合板抗剪设计中 ,除满足受冲切承载力的计算外 ,还应按所给抗剪应力公式验算叠合面上的剪应力

| Abstract: | This paper presents the shear test results of 13 specimens simply supported reinforced concrete superposed two-way slabs under concentrated load The failure patterns and behaviors of the specimens are described and analyzed The conclusions that the shear bearing capacity of superposed slab is not lower than what is cast at one time when other conditions are the same and the less concrete strength between cast-insitu and precast concreted dominates the shear bearing capacity of full slab are given The model of equal shearing strength line for superposed slabs is given too The proposed patterns and method of calculating shear bearing capacity of such elements are put forward |
