Seismic-Induced Fire Analysis of Steel-Concrete Composite Beam-to-Column Joints: Bolted Solutions
In this paper, a multi-objective advanced design methodology is proposed for steel-concrete composite moment-resisting frames. The research activity mainly focused on the design of beam-to-column joints under seismic-induced fire loading together with the definition of adequate structural details for composite columns. Thermal analyses of cross sections were performed in order to obtain internal temperature distribution; structural analyses were then carried out on the whole frame to assess the global behavior under the combined action of static and fire loadings. Furthermore, results of numerical analyses were used in order to derive information about the mechanical and numerical behavior of joints. In this paper the experimental program carried out on four beam-to-column joint specimens under seismic loading is described and results are presented and discussed together with the outcomes of numerical simulations owing to seismic and fire actions. Experimental tests demonstrated the adequacy of the seismic design. Numerical simulations showed a satisfactory performance of joints under seismic-induced fire loading.
