【摘要】：近些年地震灾害对我国造成了难以估计的经济损失和人员伤亡,尤其村镇地区的自建房破坏程度十分严重。因此,有必要对村镇建筑抗震性能的鉴定以及抗震性能的提升方面进行深入地探讨。本文以山东省的村镇建筑现状为调研对象,通过对山东省村镇建筑,尤其是自建房的系统调研,分析总结了全省各个地区村镇建筑的特点以及存在的问题,并就村镇建筑抗震性能的鉴定方法以及使用低造价隔震技术进行了分析,讨论提出了提高村镇建筑抗震能力的具体建议。其具体内容如下:(1)通过对山东省村镇建筑调研成果的梳理,总结了山东省各地区村镇建筑的结构特点以及结构类型分布,对目前存在的问题进行了分析总结。(2)在总结分析常用建筑抗震鉴定方法的基础上,基于美国的FEMA-154快速鉴定法,提出了针对村镇建筑抗震性能的实用快速鉴定方法,与我国的抗震鉴定规范进行了比较,以山东省临沂市的调研对象为例验证了其方法的可行性。(3)分析了国内外关于隔震技术的研究进展与趋势,总结了目前最具代表性的隔震技术的工作原理以及技术特点,结合村镇建筑的实际以及具体算例对比,分析讨论了低造价实用隔震技术在村镇建筑中的应用前景。(4)利用SAP 2000有限元软件对不同隔震系统的村镇建筑进行了时程分析,对比了不同隔震系统的层间剪力、层间加速度以及位移,分析讨论了其各自动力反应的特点。(5)介绍了目前主要的低造价村镇建筑隔震技术的构造措施,总结了其优点、分析了可能存在的问题,提出了进一步的设计建议。
[Abstract]:In recent years, earthquake disasters have caused inestimable economic losses and casualties in China, especially in villages and towns, where the damage to self-built houses is very serious.Therefore, it is necessary to study the evaluation and improvement of seismic performance of buildings in villages and towns.Taking the present situation of village and town architecture in Shandong Province as the research object, this paper analyzes and summarizes the characteristics and existing problems of the village and town architecture in various regions of the province through the systematic investigation of the village and town buildings in Shandong Province, especially the self-built houses.The appraisal method of seismic performance of village and town building and the application of low cost isolation technology are analyzed, and some concrete suggestions to improve the seismic capacity of village and town building are put forward.The concrete contents are as follows: (1) by combing the research results of the village and town buildings in Shandong Province, the paper summarizes the structural characteristics and the distribution of the structure types of the village and town buildings in various regions of Shandong Province.This paper analyzes and summarizes the existing problems. (2) on the basis of summing up and analyzing the commonly used seismic identification methods of buildings, and based on the rapid identification method of FEMA-154 in the United States, a practical rapid appraisal method for the seismic performance of buildings in villages and towns is put forward.Compared with the code of seismic identification in China, the feasibility of the method is verified by taking Linyi City, Shandong Province as an example. The research progress and trend of isolation technology at home and abroad are analyzed.This paper summarizes the working principle and technical characteristics of the most representative isolation technology at present, and compares the actual and concrete examples of the buildings in villages and towns.This paper analyzes and discusses the application prospect of low cost and practical isolation technology in village buildings. It makes use of SAP 2000 finite element software to analyze the time history of village buildings with different isolation systems, and compares the interstory shear forces of different isolation systems.In this paper, the acceleration and displacement between floors, the characteristics of their dynamic response are analyzed and discussed. The structural measures of the main low cost building isolation technology are introduced, and the advantages are summarized, and the possible problems are analyzed.Further design suggestions are put forward.
