To realize such an extraordinary shape, it is absolutely necessary that the connector systems have to be investigated the characteristics of the systems and analyzed with a practicable method. In this context, this research consists of not only literature research but also numerical analysis with selected connector systems, which was adopted in real free-form spatial structures. For numerical analysis, especially, finite element analysis (FEA) is performed with a various test parameter using a commercial program ANSYS. Consequently, the general characteristics of node connectors the moment-rotation-curves are presented by considering a large deformation effect as well as a multi-linear material properties.","annote":"","author":[{"family":"Hwang","given":"Kyung-Ju"},{"family":"Park","given":"Don-U"},{"family":"Park","given":"Sun-Woo"},{"family":"Knippers","given":"Jan"}],"citation-label":"hwng2007investigation","collection-editor":[{"family":"for Spatial Structures (KASS)","given":"Korean Association"}],"collection-title":"","container-author":[{"family":"for Spatial Structures (KASS)","given":"Korean Association"}],"container-title":"Journal of the Korean Association for Spatial Structures","documents":[],"edition":"","editor":[{"family":"for Spatial Structures (KASS)","given":"Korean Association"}],"event-date":{"date-parts":[["2007","jun"]],"literal":"2007"},"event-place":"","id":"4cf968b2a2a60b1f5b3e6ef6a7e2cdafitke","interhash":"470a87361328b368e268e9b06576b0e6","intrahash":"4cf968b2a2a60b1f5b3e6ef6a7e2cdaf","issue":"3","issued":{"date-parts":[["2007","jun"]],"literal":"2007"},"keyword":"2007 analysis connector engineering free-form from:petraheim hwang itke knippers node numerical park peer-reviewed spatial structur","misc":{"language":"eng"},"note":"","number":"3","number-of-pages":"8","page":"87 – 95","page-first":"87","publisher":"","publisher-place":"","status":"","title":"Investigation and Numerical Analysis of Node Connectors in Free-Form Spatial Structures","type":"article-journal","username":"itke","version":"","volume":"7"}}
