徽州传统建筑梁枋修缮加固力学分析

Numerical Simulation on Mechanical Characteristic of Beam Renovation Reinforcement of Huizhou Traditional Architecture

年代久远及多种自然灾害的影响导致各种徽州传统建筑均有不同程度的残损。为保护和传承这些珍贵的历史遗产与古迹,需要对其进行经常性维护与修缮加固。通过现场勘察,资料统计分析,归纳总结出梁枋修缮加固的主要方法。探讨了梁枋水平裂缝限值及其剜补形状问题,利用有限元方法对梁枋不同裂缝深度和宽度、剜补形状进行对比分析,得出了梁枋不同裂缝和剜补形状对结构力学特征的影响,并提出了在修缮加固计算时相关参考建议,可为徽州传统建筑的梁枋修复与保护提供参考。

Huizhou Traditional architecture is a representative of the Huizhou culture. It is also an important part of Chinese ancient architecture,but due to age- old and a variety of natural disasters,all kinds of traditional architectures of Huizhou have damaged in different degree. It is necessary to carry out regular repairs and reinforcements to protect these precious historical relics. In this paper,throughout field investigation and statistical analysis,the major strengthening methods of beam were summarized. The research studies the level crack limit and gouge patch shape of beams. It compares and analyzes the effects on structural mechanics characteristics of beam with different crack depth,width and gouge out patch shape,thus to present some measures for related calculation in the repair and reinforcement of beam. The measures have reference value for protection of traditional architecture of Huizhou.
