摘　　要：对跨度为30m的超大跨预制预应力混凝土双T板开展了足尺动力测试,并进行了人致振动舒适度分析,讨论了现有评估方法的适用性。试验结果表明,双T板的竖向基频满足PCI规范的限值要求,但其在三人屈伸工况下的加速度响应略不满足AISC DG 11规范的限值要求。考虑到振动舒适度问题,不建议将超大跨双T板应用于办公、住宅等限制严格的环境中。实际结构中双T板翼缘连接成整体后其动力学性能会得到加强,提供了较大的舒适度储备。The full-scale dynamic tests and human-induced vibration serviceability analysis were conducted on a super large-span precast prestressed concrete double-tee slab of 30m span and the applicability of existing assessment methods was discussed.The experimental results show that the vertical fundamental frequency of the double-tee slab meets the requirements of the PCI code,but the acceleration response of the double-tee slab under three-person bounce slightly does not meet the requirements of the AISC DG 11 code on vibration serviceability.Considering vibration serviceability,it is discouraged to apply the super large-span precast concrete double-tee slab in office and residence.The dynamic performance of the double-tee slab is enhanced after its flanges connected into the whole,which provides a large reserve of serviceability.
