Abstract

In designing modern composite steel-concrete structures for seismic areas buildings with ductile behaviour can be produced that are able to withstand even high-intensity earthquakes, at the cost, however, of their sustaining significant damages. In design practice, the possibility of drawing upon significant plastic resources translates into lower intensity seismic actions and therefore structural cross-sections of reduced dimensions and weights. Such advantages, when combined with ease of construction can make ductile structures the most convenient for seismic areas. This paper illustrates some solutions for the construction of high-ductility composite steel-concrete structures, in which the localization of plastic strains in the beam-to-column joints, designed to be semi-rigid and partially strength recovering, guarantees the development of global collapse mechanisms.
