摘要
以淮阳县太昊陵显仁殿为研究对象,采用数值模拟分析方法探讨结构动力特性,并对其进行多水准地震作用下的动力性能分析。结果表明:结构基本自振周期为0.826 3s,结构纵向抗侧刚度弱于横向抗侧刚度,横向抗侧刚度弱于扭转刚度;在多遇地震作用下,结构保持完好,能满足规范"小震不坏"的抗震设防目标;设防地震作用时,结构侧移较大,易发生局部破坏现象;罕遇地震作用时,木构架严重倾斜,部分山墙严重破坏甚至倒塌,导致木构架扭转变形加剧。研究结果可为显仁殿及同类建筑的维修加固提供技术支持。
Xianren temple in Taihao mausoleum was taken as the research object, to discuss the structure＇ s dy- namic characteristics and the dynamic performance analysis of multiple level earthquake by the numerical simulation analysis method. The results show that the basic natural vibration period of the structure is 0. 826 3s, longitudinal stiffness is weaker than lateral stiffness. Under the action of frequent earthquake, the structure remains intact, can meet the specification ＂no damage effects, the structure of lateral is timber frame serious tilt, part of vertical torsion deformation. The in small earthquakes＂ seismic fortification goal. When the medium earthquake larger, prone to local damage phenomenon. When the severe earthquake effects, the side wall serious damage research results can provide or even collapse, lead to the timber frame produces technical support for maintain similar buildings.
