The steel frame?center support structure system is used. With concavo?convex and irregular planes, local large?span transition of the arch, inclined columns and other irregularities, it belongs to the out?of?code high?rise building with the level A height. The stability of the mountain where the pagoda located, the spatial relationship between the figure of buddha and the pagoda and the structural arrangement of the pagoda were introduced. The layout and strengthening measures of the foundation in the mountainous region, the interaction between the figure of buddha and the structure of the pagoda,the arch?foot joint of the arch?shaped transfer trusses were analyzed. Based on design of the embedded end of the pagoda, performance?based design and other contents, including calculation of elasticity, elastic time history analysis and dynamic elasto?plastic calculation, strengthening measures were proposed for the weak parts in the structure of the pagoda.The analysis results show that the pagoda is an out?of?code high?rise building in an unfavorable area,but the structure can meet the requirements of the intended target of earthquake fortification through reasonable structural layout and perfect strengthening measures.Keywords:steel frame?center support structure system; mountain antique high?rise building; foundation design; embedded end design; seismic performance?based design; mountain stability analysis第一作者:舒紹云,碩士,高級工程師,一級注冊結(jié)構(gòu)工程師,主要從事超限高層建筑結(jié)構(gòu)、大跨空間結(jié)構(gòu)研究,Email: 37301747@ qq.com。[引用本文] 舒紹云,余晗,冷育欣,等. 東方琉璃寶塔結(jié)構(gòu)設(shè)計(jì)[ J]. 建筑結(jié)構(gòu),2022,52(12):9?16.
