摘　　要：庑殿建筑作为最高等级的古建筑形式,多用于宫殿、坛庙、重要门楼等,为研究该类建筑的抗震性能,进行了1个1/2缩尺单檐庑殿顶古建筑模型模拟地震振动台试验,获得了不同输入地震动不同水准下单檐庑殿建筑的动力响应和破坏现象,总结了柱顶石、围护墙与木构架间的相互作用、榫卯结构的变形规律等。研究表明:柱底与柱顶石间相对滑移削弱了上部结构的地震响应,减震效果良好;输入地震动强度较大时,小额枋、额枋垫板榫头轻微拔出,大额枋榫头连接牢固,木构架的整体性良好;庑殿顶与木构架间通过斗拱连接,有一定的变形能力,在保证结构整体稳定性的同时,增强了结构的耗能能力,提高了该类建筑的整体抗震性能。As the highest-class ancient buildings,the hipped roof buildings mostly used as palaces,temples and important gatehouse.To study the seismic performance of these type buildings,one 1/2 scale single eave hipped roof ancient building model has been tested by shaking table.Based on the shaking table test,the dynamic response and damage phenomenon of the model under different PGA(peak ground acceleration)were obtained,the interaction of the column top stone,infilled wall and timber structure were summarized,the deformation law of mortise and tenon structure was analyzed.The results show that the relative sliding between the column bottom and the column top stone can weaken the seismic response of the upper structure and improve the upper structure’s damping effect.When the input PGA(peak ground acceleration)is large,slight pulling-out deformation from the mortise-tenon and beam-to-column joints was observed which implied that the timber frame have good integrity due to strong connection between the primary architrave and the timber column.The dougong brackets which has good deformability can connect the hipped roof and the timber frame as one whole firmly,enhance the structure’energy dissipation ability and improved seismic performance of the hipped roof ancient buildings.
