(中国建筑标准设计研究所 北京 100044)[提要] 依据我国现行规范,对高效预应力混凝土空心板SP板的结构性能作了系统全面的研究和大量计算,与美国PCI Manual for the Design of Hollow Core Slabs的结果和国内设计研究单位的研究结果进行了比较;同时进行了试验研究,以寻找合理的设计原则,更深刻地认识SP板抗弯、抗剪性能,破坏形态,开裂荷载以及板端钢绞线锚固的性能,同时对板端与砌体连接构造措施进行了研究。综合研究结果,制定了高效预应力空心板的设计技术条件,编制了SP板国标图集。
[关键词] 高效预应力 空心板 钢绞线According to China standard, we studied the performance of SP slab which is a kind of high-strength prestressed hollow slabs.The resultS of computation are compared with the results of PCI Manual for
the Design of HolLow Core Slabs and the other research results in China. Experiments are also made in order to learn the moment-resisting, shear-resisting, failure mode, crack loads and the anchorage-bond properties of steel strands. We also have researched the joints which connect the slabs and bricks.
Keywords: high-strength; prestressed hollow slabs; steel strands
