摘要
相较于混凝土结构．木结构房屋在地震发生时，更容易破坏。考虑到木材本身的特性，以及木结构房屋的连接与混凝土结构有本质的不同．在地震作用下，有其独特的性质。本文依托振动台试验．对木结构房屋进行地震作用分析。通过对房屋不同位置加速度时程与输入时程对比．提出木结构对地震作用的放大效应。最后把不同峰值的加速度放大效应对比，定量分析了结构对地震作用的放大效应。同时也分析了放大效应与频率的关系，定性讨论了放大效应与频率的关系。为以后的木结构设计以及木结构房屋加固。提出了新的依据。
Compared to concrete structures, wood frame houses in the earthquake, more easy to destroy. Taking into account the different characteristics of the wood itself,, as well as the connection of the wooden houses and concrete structures are essentially under the earthquake, with its unique character. This article rely on the shaking table test, earthquake analysis of the wood frame houses. Through the process when the process with the input acceleration of housing at different positions contrast, the wooden structure of the amphfication effect of the earthquake. Finally, the different peak acceleration amphficatinn effect of contrast, quantitative analysis of the structure of the amphfication effect of the earthquake. Also analyzed the relationship between amplification effect and frequency, qualitative discussion of the relationship between amplification effect and frequency. A new basis for the future design of timber structures and wood frame houses reinforcement.
