As an alternative idea of ordinal seismic retrofitting method, seismic shelters are sometimes utilized. They are devices to protect human life from house collapse by inserting them inside wooden houses. However, this method has a major disadvantage that it cannot reinforce the building itself. The seismic retrofitting method by connecting shelter to existing houses with oil dampers was proposed in previous studies. In this paper, the method was extended to one-story buildings with eccentricity and to two-story buildings without enough strength on the first floor. The response control effect was confirmed by time history response analysis using the collapsing simulation program wallstat. The following results were obtained from this study: (1) In case of eccentric one-story houses, it is possible to reduce earthquake response by connecting shelter and the torsional behavior can be restrained. (2) For two-story houses, the response of the first layer can be reduced. In addition, the increase of the second layer response can be suppressed by connecting with oil dampers.","PeriodicalId":166657,"journal":{"name":"Journal of Structural Engineering B","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131954186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This isolation system is required for a large-scale disc spring to achieve both the support and isolation functions. Additionally, two methods are required: one is to control the variance of restoring force, and the other is to predict the isolation performance using a response analysis. This paper describes an optimal combination method of disc springs to absorb the variance caused by the manufacturing process by calibrating the combination using a metaheuristic algorithm. Moreover, a method to identify the variables of the hysteresis loops caused by the combined disc springs is proposed using the metaheuristic algorithm. The applicability of these methods is verified using the static loading tests data obtained by a large-scale disc spring that expands the dimensions defined by the JIS B 2706:2013 and the ISO 19690-1:2017. The static loading tests were conducted using 72 disc springs with 350 mm in diameter and six − disc springs with 700 mm in diameter. This paper demonstrates that the proposed method can control the restoring force and identify the variables required for hysteresis loops accurately and efficiently.","PeriodicalId":166657,"journal":{"name":"Journal of Structural Engineering B","volume":"22 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117278366","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
