摘　　要：文章针对一个经过抗震设计的砖混结构,制作了一个单层单开间的足尺模型,应用子结构拟动力试验技术模拟一个单层十个开间的砖混结构在地震作用下的反应,研究该结构在地震作用下的位移反应、破坏过程与形态,并给出结构的位移时程曲线和滞回性能曲线。试验结果表明,经过抗震设计的砖混结构具有非常强的抗震性能,可以抵抗地震动峰值加速度为1600gal的地震作用,远远超过"大震不倒"的设防目标,可以为提高村镇房屋抗震能力提供参考。This paper investigates the seismic behavior of a single storey ten-bay confined brick masonry structure with substructure pseudo-dynamic tests, in which only one bay of the whole structure is chosen to be the full-scale experimental test specimen. The performance of the structure in terms of displacement response, failure process and hysteresis characteristics were obtained from the tests. The test results show that the structure behaves strong seismic resistance performance, which can resist 1 600gal earthquake excitation and overwhelmingly exceeds the requirements for fortification against earthquakes. So it can give reference to improve the seismic capacity of rural houses from the tests.
