Residual Inter-story Drift Ratio (R-IDR) is another important factor that specifies the condition of building after earthquake. The values of R-IDR illustrates the possibility of retrofitting and repairing of a building. Therefore, this study aims to explore the vector-valued Intensity Measures (IMs) for predicting the R-IDR of two group of steel Moment-Resisting Frames (MRFs) with and without implementing VDs. Incremental Dynamic Analysis (IDA) was performed with considering RIDR using OpenSees software. Efficiency and sufficiency have been quantified for 18 vector-valued IMs with respect to the Residual Interstory Drift Ratio (R-IDR). Results showed that two vector-valued IMs of (Sa(T 1 ), SaRatio M-D ) and (Sa(T 1 ), I M-D ) had lower σlnSa RD |IM 2 values in the R-IDR of 0.002, 0.005, 0.01, and 0.02, and they had higher FR in the mean dispersion, (σlnSaRD|IM2)avg, compared to other IMs. In addition, two vector-valued IMs of (Sa(T 1 ), SaRatio M-D ) and (Sa(T 1 ), I M-D ) achieved p-values higher than 0.05 with respect to seismic ground motion features of M, R, and Vs30, and can be used as optimal vector-valued IMs.","PeriodicalId":101411,"journal":{"name":"International journal of structural and civil engineering research","volume":"2 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":"124226027","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}

Authors plan to introduce an automated real time seismic diagnostic system to the disaster prevention centers. This system consists of the seismometers installed in the building and observation data are saved in Internet clouds. Immediately after the earthquake, the system performs a simple diagnosis on the residual seismic performance of the building and notifies the results by e-mail. The MDOF lumped-mass model for use in the simple diagnosis is assumed to have normal tri-linear hysteretic characteristics at each story, using constants determined by referring to the analytical 3D frame model. This paper explains the proposed system and introduces the results of trial operation to the actual city hall buildings at the 2018 Osaka earthquake. After the Osaka Earthquake, the system was able to notify disaster prevention officials at the city hall of the results of the simple diagnosis within two minutes after the earthquake ended. ","PeriodicalId":101411,"journal":{"name":"International journal of structural and civil engineering research","volume":"39 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":"127287410","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}

Structures like a tall building, large span bridges, and other slender structures tend to be easily excited to high amplitudes. In order to deal with the aforementioned issues, TMD could be a good option that can reduce extreme vibration very effectively. The main objective of this paper is to show the implementation of a newly developed TMD to reduce the amplitude of vibration for an excited structure. The TMD was designed such a way that its parameters such as spring stiffness, mass can be adjusted. By tuning the early mentioned parameters, its frequency also be changed to meet the requirements from the structure. In addition, this work investigates the effect of TMD by observing the dynamic response of a two-storey frame structure both experimentally and numerically. Finite element method has been used as a numerical tool to study the dynamic response of the steel frame-TMD system. The time-history (linear) analysis of the frame without (modal mass = 0%) and with TMD (modal mass = 5 and 15%) under earthquake load has carried out and the performances are evaluated and compared. It can be concluded that a significant reduction of response (i.e. displacement) is possible via the newly developed TMD. The maximum percentage of decrease in the displacement found to be reduced by 21% for the modal mass of 5% and 43% for the modal mass of 15%, respectively. Hence, it can be noted that newly developed TMD has potential to use in the real structure for vibration mitigation. ","PeriodicalId":101411,"journal":{"name":"International journal of structural and civil engineering research","volume":"108 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":"127966202","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}
