摘要
通过预应力叠合板面内低周反复荷载的实验研究,分析了叠合板的面内剪切承载力与面内剪切刚度的变化规律,建立了板的面内剪切刚度退化表达式。试验结果表明,板的面内受力变形特性接近于现浇板,具有较好的抗震性能。
According the experimental results from six samples of prestressed concrete laminated void slab under reverse loading, the shear capacity and shear stiffness along the slab plane was investigated. This paper proposed a formula about the shear stiffness degradation of the slab. Experimental study and analysis indicated that the properties of the prestressed concrete Laminated Void Slab are close to the cast-in-site slab, and have better seismic characteristic.
