摘要
装配式建筑是我国主要发展战略目标之一。对装配式预应力预制空心楼板承载性能进行试验研究,分析不同预应力对楼板破坏模式、承载能力、荷载-位移曲线和裂缝发展的影响。随着预应力的增加,楼板承载力和开裂荷载提高,破坏模式由大变形转变为端部混凝土剪压破坏。研究成果可为实际工程提供理论依据。
Prefabricated building is one of the main development strategic targets of China. Experimental study on the load bearing behavior of prefabricated prestressed hollow slabs is carried out,analyzing the influence of prestress on the failure mode,load bearing capacity,load-displacement curve,and crack development. As the prestress increased,the load bearing capacity and crack load of slab are improved,and the failure mode is changed from large deformation to shear-compression failure of end concrete. The achievements can provide the theoretical basis for the practical engineering.
