中文摘要：

近年来，建筑信息模型（BIM）出现并蓬勃发展，它实现了建筑、结构、设备、施工及管理等方面的一体化建模，但关于BIM在古木建筑中的研究非常少见．本文基于REVIT软件，选取应县木塔进行古建筑建模技术分析，以“族”为基础，建立了阶基、台阶、华拱、泥道拱、栌斗、格子门、勾栏、屋檐、柱子、梁袱、椽、斗拱等族，完成了较为清晰、系统的模型信息．并基于．NET平台，结合REVIT API提出了斗拱建模的二次开发技术，降低斗拱创建的难度．对从REVIT中导出的杆系模型，用等效杆系模型代替斗拱，得到了有限元分析模型，通过SAP2000分析了木塔在风、地震等外力作用下的整体力学性能．文章对其他古木建筑的BIM建模技术及结构分析具有参考价值．

英文摘要：

In recent years, Building Information Modeling （BIM） technology was created and boomed because of itsability to integrate the modeling analysis of architecture, structure, facility, construction and management.However, BIM has not been commonly used in creating models of historic timber architecture. The present workused REVIT to create the models of Yingxian wooden tower, on the base of family. Details like Jieji. Taijie.Huagong. Nidaogong. Ludou. Gezimen. Goulan. Wuyan, Zhuzi. Liangfu. Chuan. Dougong were created and clear andsystematic model information was established. Based on. NET platform and REVIT API, the method of creatingDouGong by parameterization come up, reducing the difficulty of the work. As for the frame system modelexported from REVIT, an equivalent member system model was used to replace the Dougong structure and a finiteelement analytical model was established. Finally, the overall mechanical properties of Yingxian Wooden Towerunder earthquake and wind action was analyzed by SAP2000. The paper will work for the application of BIM inmodeling and the structure analysis.
