摘　　要：回顾并评述了用钢筋网水泥砂浆加固墙体的国内外研究现状,为了研究在地震作用时这种加固方法的抗震性能,进行了两个砖砌体模型(一个加固试件JZF;另一个未加固试件ZF)的振动台模拟地震的对比试验。通过利用模态分析和系统识别的方法,对试件JZF及ZF的动力特性进行了分析。在分析的过程中,提出了普通砌体和“夹板墙”加固墙体的初始刚度计算公式。最后利用系统识别出的试件JZF及ZF的结构参数,模拟了试件JZF及ZF在具有不同频谱特性地震波记录情况下的反应。The static of art research on brick building strengthened with cement mortar reinforced with steel mesh are reviewed and evaluted to study the earthquake-resistant behavior of this kind of structures, two brick building models-one is strengthened and the other is unstrengthened for comparison, are experimented on the earthquake simulating shaking table. The method of mode-shape analysis and system identification are used to analyse the dynamic behavior of both models and the formula of the preliminary rigidity for the brick building strengthened with cement mortar rein- forced with steel mesh is advanced. By the method of using the system identification, the structural parameters of both models are recognized at last and their response to the seismic wave with different characteristic of spectrum are simulated.
