Steel-concrete composite full strength joints with concrete filled tubes:design and test results
In this paper, a multi-objective advanced design methodology dealing with seismic actions followed by fire on steel-concrete composite full strength joints with concrete filled tubes is proposed instead of a traditional single-objective design where fire safety and seismic safety are achieved independently. Experimental tests together with numerical simulations of the fire behaviour were carried out to derive fundamental information about the performance of these joints. In detail a total of six specimens designed according to Eurocode 3,4 and Eurocode 8 were subjected to monotonic and cyclic loadings up to collapse at the Laboratory for Materials and Structures Testing of the University of Trento, Italy. These specimens were detailed in order to exhibit a favourable fire behaviour after a severe earthquake. The major aspects of the cyclic behaviour of composite joints are presented and commented upon together with fire analysis results. Both the experimental activity and the numerical FE simulations demonstrate the adequacy of the proposed joint design.
