摘要

介绍了轻型木结构足尺模型振动台试验以及美国、加拿大、中国规范关于轻型木结构房屋基本周期估算公式,讨论了剪力墙刚度、激振程度及扭转等因素对基本自振周期的影响,并比较了试验值与估算值.结果表明,房屋基本周期与上述因素密切相关,仅考虑房屋的高度是不够的;建议针对3层及以下的轻型木结构房屋,地震影响系数直接采用反应谱曲线中最大值.
The paper presents a brief introduction to the full-scale wood-framed house shaking table test and the proposed formulas in the Codes of USA,Canada and China.Based on the test data,a study is done on the effect of the shear wall stiffness,amplitude of ground excitation and configuration of the structure on the fundamental periods of viberation of the wood-framed house.The result of the comparison between the test data and calculated values proves the influence and accordingly shows the height of a building is not the only factor to be taken into account of the fundamental periods of viberation.As a result,the earthquake coefficients of the 3-storeyed or lower wood-framed houses are proposed to adopt the maximum value of the earthquake response spectrum curve.
