无粘结预应力板墙结构的强度与变形性能

Experimental Research on Strength and Deformability of Slab and Wall Structure with Unbouncd Prestressing in the Slab

通过低周往复水平荷载试验，对无粘结预应力板墙结构的工作特性，以及无粘结预应力筋在水平荷载下的变化规律进行了分析．讨论了墙内配筋率与结构强度和变形性能的关系，及其对板墙结构破坏机理的影响．

Rased on the experimental researches, the characteristic behavior of slab and wall structure with unbounded prestressing in the slab under low frequency cyclic loading have been studied. The effect of magnitude of reinforcement in the wail on the failure mechanism, the strength and the deformability, as well as the stress variation of the unbotinded prestressing are careffally investigated.
