新疆南疆地区传统土坯房屋震害及抗震技术措施

SEISMIC DAMAGE AND SEISMIC COUNTERMEASURES OF XINJIANG TRADITIONAL ADOBE HOUSE

通过对近几年来历次大地震中新疆村镇土坯房屋的震害总结,归结了此类结构在地震中易于受损的原因:构件强度不足、节点连接弱、结构体系稳定差等,从中提出适合于当地经济发展的加固方案,也即:木柱梁-土坯组合墙结构体系,其目的是在不增加或少增加造价的前提下,以简便易行的手段提高新疆土坯房屋结构的抗震能力。

Based on the summarization of seismic hazard of abode house in the village and towns of Xinjiang Autonomous Region in recent years,the fragilities of abode house during the earthquake are reduced to some aspects,such as insufficient components' capacities,weakness in joint and connection,instabilities of structural framework,etc.Then a strengthened scherne,i.e.the timber column and beam-adobe composite wall is put forward according to local economics so as to improve the seismic capacity of abode house under the premise of no increased cost or less increased cost with simple and feasible measures.
