基于有限单元法的优秀历史建筑屋架设计分析

FEM Based Design Analysis of the Roof Truss of an Excellent Historical Architecture

以工程实例为背景,分析了该优秀历史建筑原设计者的主屋架结构设计过程。并以有限单元法对最终的屋架结构进行了受力分析,并为后步的修缮加固提供依据,以期对钢木屋架类似项目有所技术参考。

The design process of the main roof truss structure of the original designer of this excellent historical architecture is analyzed under the background of engineering example. And stress analysis is carried out with FEM （finite element method） to the final roof truss structure for providing basis for repair and reinforcement in later phase as well as providing technical references for similar steel and wooden roof truss engineering.
