［摘要］洛陽隋唐城應(yīng)天門遺址保護(hù)建筑平面呈凹形布置，結(jié)構(gòu)分縫后分為中部城樓、東西飛廊+朵樓+連廊、東西闕樓5個(gè)結(jié)構(gòu)區(qū)段。為避讓遺址和展示古代建筑形態(tài)，結(jié)構(gòu)體系下部采用單跨斜柱支撐結(jié)構(gòu)，中部采用空間桁架轉(zhuǎn)換結(jié)構(gòu)支撐上部框架結(jié)構(gòu)，屬于平面和豎向不規(guī)則體系。介紹了典型單體中部城樓區(qū)段、西飛廊+朵樓+連廊區(qū)段、西闕樓區(qū)段的設(shè)計(jì)方案、結(jié)構(gòu)特點(diǎn)、分析結(jié)果及抗震設(shè)計(jì)原則。對(duì)各結(jié)構(gòu)單體分別采用靜力彈塑性分析、動(dòng)力彈塑性分析方法進(jìn)行罕遇地震作用下彈塑性分析，結(jié)果表明兩種分析方法結(jié)果吻合，結(jié)構(gòu)能夠滿足預(yù)期抗震性能目標(biāo)。采用Push down分析方法考察下部遺址層在豎向荷載作用下的承載能力，結(jié)果表明下部遺址層具有足夠的承載能力及塑性變形能力。

Abstract: The plane of the conservation building of YingTianMen archaeological site of Luoyang City of Sui and Tang Dynasties is in the shape of the Chinese character “凹”. The structure is divided into five structural sections: middle tower, east and west Duolou and east and west Quelou. In order to avoid the site and display the ancient architectural form, the structural system adopts the single-span inclined column support structure in the lower part and the space truss transformation structure in the middle part to support the upper frame structure, which belongs to the  plane and vertical irregularity system. The design scheme, structural characteristics, analysis results and seismic design principles of typical section as middle tower section, West Flying Corridor+Duolou+connecting corridor section and West Quelou section were introduced. The static elastoplastic analysis and dynamic elastoplastic analysis method were used for the elastoplastic analysis of each structure under rare earthquake action, respectively. The results of the two analysis methods are consistent, which shows that the structure can meet the expected seismic performance goal. Push down analysis method was used to investigate the bearing capacity of the lower site layer under vertical load. The results show that the lower site layer has sufficient bearing capacity and plastic deformation capacity. 

Keywords:YingTianMen archaeological site of Luoyang City of Sui and Tang Dynasties； conservation building of archaeological site； vertical irregularity； seismic design； elastoplastic analysis
