斗拱属我国古建筑的典型构造特征，其力学性能影响结构安全。为保护古建筑，基于文献检索方法，研究了古建筑木结构斗拱的力学性能在国内外的研究现状，对已取得的成果及不足之处进行了合理评价，并展望了未来发展趋势。结果表明：二十多年来，国内外已从理论及试验角度充分开展斗拱的力学性能研究，对斗拱在静动力作用下的力-变形特征、破坏形式及地震作用下的抗震耗能机理进行了较为深入探讨，剖析了斗拱受力机制，建立了斗拱力学简化模型。但现有研究也存在斗拱选取范围有限、斗拱的协同作用、残损机制及加固方法研究不足等问题。随着科技发展和研究水平的提高，斗拱力学性能将逐步得到全面揭示，研究成果也将逐步在古建筑保护过程中得以体现。%Tou-kung (bracket set ) belongs to the typical constitution characteristics of Chinese ancient wood buildings , whose mechanical performances relate closely to the safety of whole structure .To protect Chinese ancient buildings ,the advances in the research of tou-kung’s mechanical performances were analyzed based on document retrieval methods ,the achievements as well as the disadvantages of the researches were evaluated rationally ,and the research developments were expected .The results show that the researches of tou-kung’s mechanical performances have been carried out for more than 20 years by theoretical as well as experimental means ,the mechanical performances of tou-kung such as force-dis-placement relationship ,damage type ,earthquake energy dissipation mechanism and so on have been discussed ,and its analytical model have been built .However ,there exist some problems in present research such as the limited selection of tou-kung type ,and the lack of researches in tou-kung’s cooperation action ,damage mechanism and strengthening meth-ods .With the development of science and technology as well as research level ,the mechanical performances of tou-kung will be roundly discovered ,and the achievements in its research will be gradually applied in the protection of Chinese an-cient wood buildings .
