Thermal–stress analysis of a three-dimensional end-plate steel joint

Summarization: In this article the behaviour of an extended end-plate steel connection under elevated temperatures is studied using three-dimensional non-linear finite elements with unilateral contact and friction interfaces. The behaviour of the connection up to collapse has been studied. Within this study, the influence of the sequence between thermal–mechanical loads, the opening of the interface as well as the representation of the shear forces transmitted through friction and bolts, are investigated. Useful results relevant to fire-structure interaction and the validation of simplified models, are presented.Παρουσιάστηκε στο: Construction and Building Material
