［摘要］為了研究清代九檁大式殿堂在地震作用下的彈塑性特性，根據(jù)《清式營(yíng)造則例》清代九檁大式殿堂真實(shí)的結(jié)構(gòu)工藝做法，建立了一個(gè)帶斗拱、帶側(cè)腳的清代九檁大式殿堂模型，對(duì)該殿堂體系進(jìn)行了彈塑性加速度反應(yīng)和位移反應(yīng)分析。在分析過(guò)程中考慮了木結(jié)構(gòu)材料的各向異性、斗拱的減振作用、榫卯節(jié)點(diǎn)的連接特性、柱與礎(chǔ)石之間的摩擦耗能作用、側(cè)腳和生起的作用，并全面考慮了清代九檁大式殿堂所有的結(jié)構(gòu)特性。分析結(jié)果能較真實(shí)地反映清代九檁大式殿堂在地震作用下的結(jié)構(gòu)反應(yīng)。

Abstract: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.
Keywords:structure engineering; ancient architecture; dynamic analysis; timber structure; DouGong
