传统民居抗震隔震研究

Research on Seismic Isolation and Isolation of Traditional Residential Buildings

摘要: 传统木结构民居以榫卯节点、斗拱层隔震等构造展现出独特的抗震智慧，但其材料老化、节点刚度退化等问题导致抗震性能下降。本文通过文献分析与实验研究，系统对比传统抗震机理与现代加固技术的效果。采用缩尺模型振动台试验、低周往复加载试验及有限元模拟方法，验证碳纤维布(CFRP)、嵌槽配筋砂浆带等现代技术的增强作用。结果表明，传统构造的柔性耗能与现代材料的高强度结合，可显著提升结构整体性与抗震性能，实现“小震不坏、中震可修、大震不倒”的设防目标。

Abstract: Traditional wooden residential buildings demonstrate unique seismic resistance wisdom through their Mortise-and-Tenon joints and Dou Gong tiered isolation structures. However, issues such as material ageing and degradation of joint stiffness have led to a decline in seismic performance. This paper systematically compares the effects of traditional seismic mechanisms and modern reinforcement techniques through literature analysis and experimental research. Using scaled model shaking table tests, low-cycle repeated loading tests, and finite element simulation methods, the enhancing effects of modern technologies such as Carbon Fibre Reinforced Polymer (CFRP) and groove reinforced mortar strips are validated. The results indicate that the combination of the flexible energy dissipation of traditional structures with the high strength of modern materials can significantly improve overall structural integrity and seismic performance, achieving the goal of being “untouched by minor earthquakes, repairable after medium earthquakes, and uncollapsed in major earthquakes”.
