摘要
为了研究清代九檩大式殿堂在地震作用下的弹塑性特性,根据《清式营造则例》清代九檩大式殿堂真实的结构工艺做法,建立了一个带斗拱、带侧脚的清代九檩大式殿堂模型,对该殿堂体系进行了弹塑性加速度反应和位移反应分析。在分析过程中考虑了木结构材料的各向异性、斗拱的减振作用、榫卯节点的连接特性、柱与础石之间的摩擦耗能作用、侧脚和生起的作用,并全面考虑了清代九檩大式殿堂所有的结构特性。分析结果能较真实地反映清代九檩大式殿堂在地震作用下的结构反应。
For research on the elasto-plastic character of timber frame palace with nine-purlins in Qing Dynasty under the impacting of earthquake, a model of the structure with DouGong and CeJiao is built in accordance with the real craftwork for the structure and Examples of Engineering Practice in Qing Dynasty. After that, the finite analysis method is conduced. The elasto-plastic responses of its acceleration and displacement are analyzed under the impaction of different earthquakes. The analysis and evaluation for the system is developed from the view of structure. Such characteristics as anisotropy of wooden material, damping effect of DouGong, connection behavior of the mortise-tenon joint, energy dissipation between the column and the base through friction and the effect of CeJiao and ShengQi are conducted. So the responses of the structure under the impaction of earthquake are expressed more really.
