摘要：汉皇祖陵祭祀明台为一座根祖祭祀的汉文化建筑，为一层台基上托着上大下小的方斗形建筑，方斗形建筑由四周外斜墙和顶部圆形构件组成。针对该文化建筑的造型特点，结构方案采用下部台基混凝土框架-剪力墙结构+上部外斜钢柱-双向空间钢桁架的混合结构体系，并在设计中采用多种结构计算程序对其进行计算分析。采用3D3S和MIDAS Gen软件计算上部外斜钢柱-双向空间钢桁架，采用PKPM软件计算下部台基混凝土框架-剪力墙结构，采用MIDAS Gen软件对下部台基混凝土框架-剪力墙结构+上部外斜钢柱-双向空间钢桁架的混合结构进行整体分析，采用MIDAS FFA对关键节点进行应力分析。通过对结构方案对比选型、结构计算、混凝土与钢结构之间的连接等论述，针对工程结构特点，结合抗震规范要求，提出大跨度部分采用受力更好自重更小的双向钢桁架、支座采用传力更直接的耳板连接、外斜钢柱下插底部的混凝土巨柱等若干适当技术措施，使主体结构具有较好的承载力和变形能力，找出结构潜在薄弱环节，降低现场施工难度。

Abstract: The Han Emperor Dynasty Sacrifice Hall is a Han cultural building worshipped by the ancestors. It is a square bucket-shaped building with a large upper and small lower base. The square bucket-shaped building is composed of inclined walls around and circular components at the top. According to the modeling characteristics of the cultural building, the structural scheme adopted the hybrid structural system of the lower platform concrete frame-shear wall structure+the upper inclined steel column-the two-way space steel truss, and adopted various structural calculation procedures to calculate and analyze it in the design. 3 D3 S and MIDAS Gen softwares were used to calculate the upper inclined steel column and bidirectional spatial steel truss. PKPM software was used to calculate the lower platform concrete frame-shear wall structure. MIDAS Gen software was used to analyze the hybrid structure of the lower platform concrete frame-shear wall structure + the upper inclined steel column-the two-way space steel truss. Von Mises software was used to analyze the stress of the key nodes. Based on the discussion of the comparison of structural schemes, structural calculation, and connection between concrete and steel structure, and in view of the characteristics of engineering structures, combined with the requirements of seismic code, some appropriate technical measures were proposed, such as the use of two-way space steel truss with better stress and smaller self-weight in the large-span part, the use of ear plate connection with more direct force transmission in the support, and the insertion of concrete mega column at the bottom of the outer inclined steel column, so as to make the main structure have better bearing capacity and deformation capacity, identify the potential weak links of the structure, and reduce the difficulty of field construction.

Keywords: hybrid structure; comparison of structural scheme; node design; two-way space steel truss
