Abstract

Post and lintel frame is a prominent architectural structure in Chinese temple architecture, characterized by its wooden construction. Mortise–tenon joints (MTJs) serve as the primary connection method for these wooden structures, employing straight mortise nodes (SMNs) and through-mortise joints (TMNs). This study presents a method that utilizes wooden pins to reinforce MTJs, enhancing the seismic performance of timber frame structures. Finite element (FE) simulation verifies the effectiveness of wooden pins in reinforcing both SMNs and TMNs, leading to improved load-bearing capacity and ductility of the MTJs. Additionally, the study confirms that reinforced nodes help to restrict the displacement changes within the wooden frame. The paper also investigates the optimal distribution of MTJs reinforced by the wooden pins throughout the structure, with the aim of enhancing the wood frame’s seismic performance. The results show the bearing capacity of MJT reinforced with wooden pins is approximately 11.3% higher compared to that of MTJ without reinforcement. The reinforcement of wood pins effectively controls the horizontal displacement of the overall structure of the wooden frame, which is reduced by about 50%–62% compared with the unreinforced wooden frame. The locating the wooden pin-reinforced MTJs in the outer columns and middle layer columns reduces the structural displacement, which is 31.53% in X direction, 5% in Y direction, and 25.86% in Z direction.

中国古代木结构寺庙的木销加固：大雄宝殿案例

柱楣架是中国寺庙建筑中一种突出的建筑结构，其特点是木质结构。榫卯结构（MTJ）是这些木结构的主要连接方法，采用直榫节点（SMN）和通榫节点（TMN）。本研究提出了一种利用木销加固 MTJ 的方法，以提高木框架结构的抗震性能。有限元（FE）模拟验证了木钉加固 SMN 和 TMN 的有效性，从而提高了 MTJ 的承载能力和延展性。此外，研究还证实，加固节点有助于限制木框架内的位移变化。本文还研究了由木销加固的 MTJ 在整个结构中的最佳分布，目的是提高木框架的抗震性能。结果表明，与未加固的 MTJ 相比，使用木钉加固的 MJT 的承载能力提高了约 11.3%。木销加固有效控制了木框架整体结构的水平位移，与未加固的木框架相比，水平位移减少了约 50%-62%。将木销加固的 MTJ 设置在外层柱和中层柱，可减少结构位移，X 方向位移减少 31.53%，Y 方向位移减少 5%，Z 方向位移减少 25.86%。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
