【摘要】：徽州古民居是徽州传统建筑的典型代表,蕴含着深厚的文化地域特色,凝结着古徽州人文化修养、审美需求、价值取向。其主体结构的材料主要是砖、木、石,连接方式主要是榫卯连接,结构合理,技艺巧妙,不管是在总体规划上其风格自成一家,就连单个建筑的平面或者空间上处理以及雕刻艺术的采用也是极具皖南本地特色。所处地理位置更使得它们蕴含当地文化精华与山川灵气,建成的结构被中外建筑师们叹为观止。然而,就目前来说徽州古民居建筑业面临着严重的破坏。分析徽州古民居破坏的原因时,不仅要考虑由于年代久远所造成的的木材老化,还要分析古民居的震害特点。卯榫连接方式对于古民居具有良好的稳定性能发挥着不可替代的作用,所以要研究出对徽州古民居卯榫节点加固修缮确实可行的办法。基于这一点,本文主要对徽州古民居中榫卯节点加固方法进行研究。本文主要内容与研究成果如下:(1)本文在查阅大量文献与资料和实地调研的基础上阐述了徽州传统民居震害特点和卯榫节点破损形式,对其受力破坏机理及耗能能力进行分析。(2)总结归纳了徽州古民居卯榫节点的加固措施。(3)选取单跨的徽州古民居的木构架为原型,通过计算和有限元分析的方法对榫卯节点加固前后进行受力变化分析。(4)通过卯榫节点加固前后受力性能对比,加固后的卯榫节点的受力性能明显提高。验证了扁钢和碳纤维布加固的可行性,为今后徽州传统建筑的修复与保护提供参考。
[Abstract]:Huizhou ancient residence is a typical representative of Huizhou traditional architecture, which contains profound cultural regional characteristics, condenses ancient Huizhou people's cultural accomplishment, aesthetic demand and value orientation.The materials of its main structure are mainly brick, wood, stone, and the main way of connection is tenon and joint. The structure is reasonable and the skill is clever, regardless of its own style in the overall planning,Even the plane or space of a single building, as well as the use of engraving art is extremely local features of southern Anhui.Because of their geographical location, they contain the essence of local culture and the spirit of mountains and rivers, and their structures are breathed by Chinese and foreign architects.However, at present, Huizhou ancient residential construction industry is faced with serious damage.When analyzing the causes of the destruction of ancient residential buildings in Huizhou, not only the aging of wood caused by old age should be considered, but also the characteristics of earthquake damage of ancient houses should be analyzed.Tenon joint plays an irreplaceable role in the stability of ancient residential buildings, so it is feasible to study the reinforcement and repair of tenon joints of ancient residential houses in Huizhou.Based on this, this paper mainly studies the tenon joint reinforcement method of Huizhou ancient residence.The main contents and research results of this paper are as follows: (1) on the basis of consulting a large number of documents and materials and field investigation, this paper expounds the characteristics of earthquake damage of traditional residential buildings in Huizhou and the form of joint breakage.In this paper, the mechanism of mechanical failure and energy dissipation ability are analyzed. 2) the reinforcement measures of joint tenon and tenon joint of ancient Huizhou dwelling are summarized. (3) the single span wooden frame of ancient Huizhou dwelling is selected as the prototype.By means of calculation and finite element analysis, the stress changes of tenon joints before and after reinforcement are analyzed. 4) by comparing the mechanical behavior of tenon joints before and after strengthening, the mechanical performance of the joints strengthened is improved obviously.The feasibility of reinforcing flat steel and carbon fiber sheet is verified, which provides a reference for the restoration and protection of Huizhou traditional buildings in the future.
