村镇装配砌体抗震性能试验

Testing on Seismic Performance of Villages Assembly Masonry

通过对墙体低周反复荷载作用试验,观察墙体的工作过程和破坏形态,分析墙体在不同状态下,承受低周反复水平静力荷载时的力学性能以及墙体的延性、归一骨架曲线及刚度等特性。并得出装配式砌体墙的延性、抗剪承载力以及耗能能力均可以达到规范要求,适合在处于各地震区的村镇低层建筑中推广使用。

The working process and the failure pattern of the walls under low reversed cyclic loading test was ob- served in this paper. Mechanical properties, ductility, skeleton curve and stiffness and other characteristics of the walls under horizontal low cyclic static load have been analyzed. It was suggested that shear capacity, ductility and energy dissipation capacity of the fabricated masonry wall can reach to the standard requirement, and be suitable for utilization in low-rise buildings in town at earthquake zone.
