摘要:东方琉璃宝塔为山地仿古高层建筑,塔身共七层,高86m,采用钢框架-中心支撑结构体系,存在平面凹凸不规则、局部拱形大跨转换、斜柱等多项不规则,属于A级高度的超限高层建筑。介绍了宝塔所处山体稳定情况、佛像与宝塔的空间关系以及宝塔的结构布置,并针对山地基础布置及加强措施、佛像与宝塔结构之间相互影响以及拱形转换桁架拱脚节点进行了分析。基于宝塔嵌固端设计、性能化设计及其他项目,包括弹性计算、弹性时程分析和动力弹塑性计算等内容,对宝塔结构薄弱部位提出针对性的加强措施。分析结果表明,宝塔为处于不利地段的超限高层建筑,但通过合理的结构布置和完善的加强措施,能使结构满足设计预定的抗震设防目标的要求。

Abstract: The Dongfang Glazed Pagoda is an mountain antique high-rise building with a total of seven stories and a height of 86 meters. 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.
