The friction-added ceiling system incorporated a novel rotational friction mechanism and its effectiveness was demonstrated through a series of shake-table tests. The primary focus of this study was to evaluate the effects of key governing parameters of the friction-added ceiling system, with due consideration for the dynamic characteristics of supporting structures. Firstly, based on a total of 6 building models, the effects of structural dynamic properties on the peak floor acceleration (PFA) were evaluated. The analysis results showed that the in-structure amplification (PFA/PGA) was higher for concentrically braced frames (CBF) compared to the moment-resisting frames (MRF) due to the relatively short-period characteristics inherent to CBFs. It was also observed that the PFA reduction caused by structural nonlinearities was more pronounced for CBFs because of their drastic elongation of fundamental period. The friction-added ceiling systems showed reduced displacement response as the friction force increased. The effectiveness of the friction-added ceiling systems was only minimally influenced by the length of the hanger wires and the angle of damper braces, implying the versatility of the system to various design and installation conditions. Various response characteristics of friction-added ceiling systems considering structural nonlinearities was also presented.","PeriodicalId":472967,"journal":{"name":"Journal of Korean Society of Steel Construction","volume":"32 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140413163","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}
