［摘要］大唐芙蓉园西大门是典型的传统风格建筑，系统阐述了西大门的门楼和三出阙的结构特点，结合结构分析的计算结果，给出了门楼和三出阙结构体系的优化过程。通过选择合理的结构设计方案，将三出阙的屋盖体系分解为“基本部分”和“附属部分”，简化结构计算，通过调整相应的构造措施，减小屋面“错层”带来的不利影响。同时文中也给出若干关键部位的设计，为该类建筑的进一步分析提供了思路和方法。

Abstract: The west gate of Tang Paradise is a typically architecture with traditional style. The structural characteristics of the gate building and the three-tier gate tower of the west gate were systematically expatiated. Based on the calculation results of the structural analysis, the optimization process of the gate building and the three-tier gate tower structural system was given. By selecting a reasonable structural design scheme, the roof of three-tier gate tower was decomposed into “basic parts”and “ancillary parts” to simplify structural calculations, and then the corresponding construction measures were adjusted to reduce the adverse effects brought  by the split-level roofs. Some structural designs of key components were given, which provided the ideas and methods for further analysis of such buildings.

Keywords: traditional style architecture; gate building; three-tier gate tower; structural design
