Abstract: Prestressed rib-tile is a kind of new roof structure with "V"section. Testing of its mechanical properties shows that it has high crack resistance, high permissible applied loads and ductility. Our investigation will provide more reasonable data in the further design, calculation and construction.

Key words: prestressed rib-tile, loss of prestress, wooden comb reinforced slab, crack resistance, load-bearing capacity, ductility

摘要： 预应力肋壳瓦是一种异形截面"V"的新型屋面结构,力学性能测试结果表明,预应力肋壳瓦具有良好的抗裂性、承载能力和延性。研究结果也为进一步完善预应力肋壳瓦的设计理论、计算和施工提供有益的资料。
