摘要
目前我国仍存在大量生土建筑房屋,其中不乏以群落形式存在的民居。为了保护居民的生命安全和历史文化遗产,亟需提高该类房屋的抗地震倒塌能力。针对群落生土建筑的特点,本文提出了采用薄壁型钢条带加固生土墙体并采用角钢加固屋盖和独立柱的加固方案,该方案便于施工且节约成本。为验证加固方案的有效性,选取一典型生土建筑,通过数值仿真动力计算方法进行地震倒塌过程分析,对比分析其在加固前后的响应,结果表明,采用本文提出的加固措施能显著提高生土建筑的抗地震倒塌能力。
At present,a great number of raw-soil architectures still exist in our country,most of which survived as the residential building group. in order to protect the inhabitants＇ life safety as well as the historical and cultural heritage,the capability of seismic collapse resistance of these buildings is needed to improve. According to the peculiarity of residential building group,the strengthening measure,which mainly consists of reinforcing the raw-soil wall with thin-walled steel stripes and fastening the roof and column with angle steels,is proposed,it has the advantages of both convenient construction and low cost. for verifying the effectiveness of the strengthening measure,a typical raw-soil building is selected to conduct a numerical simulation on seismic collapse process. By comparing the calculation results,it is indicated that the proposed strengthening measure could enhance the seismic collapse resistant capacity obviously.
