摘要

按照云南“一颗印”构造要求制作了一个两层传统穿斗式木结构房屋模型进行模拟振动台试验。对结构模型的破坏模式、动力响应、应变响应，扭转效应、剪力分布、弯矩变化及耗能能力进行了分析研究。结果表明:结构模型满足中国建筑抗震设计规范“小震不坏、中震可修、大震不倒”的要求；结构模型具有明显扭转效应；层间剪力分布取决于质量分布；弯矩随地震激励增大不断增大，结构模型未发生塑形破坏；层间累积耗能能力一层耗能能力最大，二层次之，屋脊最小。

Abstract

Shaking table tests for a model of a two-storey Chuan-Dou timber building constructed according to the requirement of Yi-Ke-Yin of Yunnan Province were conducted. Its failure pattern, dynamic response, strain response, torsional effect, shear force distribution, bending moment variation and energy dissipation capability were analyzed. The results showed that the structural model meets the design requirements of no damage under frequent earthquakes,repairable under moderate earthquakes and no collapse under rare earthquakes; the structural model has an obvious torsional effect; inter-story shear force distribution depends on mass distribution; the models bending moment increases with increase in earthquake excitation; there was no plastic damage in the structural model; the inter-story energy dissipation capacity is the largest at the first floor, latger at the second floor and the smallest at the roof.
