[摘要] 通过对一榀两层两跨预压装配式混凝土框架在低周反复荷载作用下的试验，研究了预压装配式混凝土框架的承载能力、破坏形态、滞回性能、变形恢复能力、位移延性及耗能能力等抗震性能。试验研究表明：加载过程中，框架梁端首先出现塑性铰，预压装配式框架属“强柱弱梁”型结构。框架荷载一位移滞回曲线较为丰满，具有良好的耗能能力和较强的变形恢复能力，实测的框架各层位移延性系数在3.67~4.44之间，预压装配式混凝土框架具有良好的延性性能。

Abstract: Based on the low-reversed cyclic loading experimental study of a specimen of two floor double-span prestressed fabricated concrete frame, the seismic performance such as bearing capacity, failure mode, hysteretic behavior, deformation recovery capacity, ductility, energy dissipation capacity, etc were researched. The experiment indicated that the plastic lunge firstly appeared at the end of the beams in the loading process and the prestressed fabricated concrete frame is a kind of 'strong column weak beam'  structure. The load-displacement hysteretic curve is full and shows excellent energy dissipation and deformation recovery capacity. The ductility coefficient based on the experiment result is between 3. 67 and 4.44; the prestressed fabricated concrete frame shows excellent ductility.
