洛阳隋唐城天堂遗址保护建筑结构设计
[摘要] 洛阳市隋唐城天堂遗址保护展示建筑为古文物保护建筑，结构设计在首层采用54米跨度桁架转换结构，托起上部57米高仿古塔建筑。采用大跨度转换结构方案，实现在遗址有效范围内不落基础的古建保护设计思想，有效保护原址上的遗存物。分析转换结构的选型，整体结构的特性，重要节点有限元分析及重要构件验算标准。

Structure design of Tiantang for the protection of the ruins of ancient buildings which built in SuiTang Dynasty in Luoyang City
Abstract：Tiantang is the protection of the ruins of ancient buildings which built in SuiTang Dynasty in Luoyang City, 54 meters span truss conversion structure is taken on the first floor adopts in structure design which can hold 57 meters high upper archaize tower buildings. Big span conversion structure is used to meet the thought of protecting ancient building effectively. The type of the conversion structure , the characteristics of the whole structure, the important node finite element analysis and the important component checking standard is studied in the paper.
Keywords: the big site; ancient for the protection of building; 54 meters span truss conversion structure; eigenvalue analysis; Pushdown
