Study on promotion for seismic reinforcement of wood-frame houses built in snowy region

在本研究中，为了积累促进雪区木结构房屋抗震加固的技术数据，作者对雪期房屋的抗震性能进行了研究。首先，基于地震诊断对当前状态下的抗震性能进行了检测。研究了保温改善与房屋抗震性能的关系。在此基础上，分析了房屋地震反应与强运动下屋雪动力特性的关系。结果表明，在考虑雪荷载的情况下，通过保温改善可以保持结构的抗震性能。结果表明，屋面积雪的动力特性降低了房屋的运动。

In this study, to accumulate technical data for promotion of seismic reinforcement on wood-frame houses built in snowy region, the author examined seismic performance of the houses during snow season. First, seismic performance in current state was examined based on seismic diagnosis. Relationship between insulation improvement and seismic performance of the houses was examined also. Then, relationship between seismic response of the houses and dynamic behavior of roof snow caused by strong motion was examined. As the results, it was possible to maintain the seismic performance considering snow load by the insulation improvement. And it was found that the dynamic behavior of roof snow decreased motion of the houses.
