对一幢复杂高层钢－混凝土组合门式结构消能减震体系的1/30缩尺模型进行了模拟地震振动台试验，深入研究了该结构的动力特性和地震反应特征，通过比较验证了粘滞阻尼器的减震效果。结果表明：结构整体空间作用显著，两座塔楼之间扭转反应较大。有、无阻尼器结构的各项反应基本满足抗震规范的要求；从平均意义上讲，阻尼器对整体结构的位移反应有一定的控制效果，对结构高空连廊的位移和两座塔楼之间的扭转反应控制效果较好。

In this paper, a 1/30 scale model of high-rise portal-shaped steel-concrete hybird building with viscous dampers is tested on shaking table to study the dynamic characteristics, seismic response and the effect of dampers on seismic behaviors of the structure. Test results show that the torion responses between tower 1 and tower 2 is obviously, but the seismic response of the whole structure meet the code requirement. The dampers play an important role in energy dissipation, and the displacement of high-altitude gallery and the tortion response of two towers are greatly reduced.
