Seismic-Induced Fire Analysis of Steel-Concrete Composite Beam-to-Column Joints: Welded Solutions
A multi-objective design methodology dealing with seismic-induced fire on steel-concrete composite moment resisting frames endowed with concrete filled tubes (CFT) full strength joints is presented in this paper. In order to achieve these goals analytical and FE simulations including thermal analyses were carried out to design the proposed joints: this was followed by experimental tests under monotonic and cyclic loadings. Preliminary, seismic and fire analyses provided valuable information on the performance of moment resisting frames endowed with the chosen joint typology. A total of six specimens was designed and subjected to lateral loads. The specimens were subassemblages of interior beam-to-column joints connected by means of welded connections. Relevant experimental results are presented and commented. Furthermore, since the scope of the project was to promote joint typologies able to survive a seismic-induced fire, specimens were damaged by imposing monotonic loads equivalent to damage induced by seismic excitations, before being subjected to fire loadings. Thus, valuable information was obtained about the endurance of the proposed joint typology.
