Fast construction of structural walls made of reinforced concrete for buildings or industrial warehouses in single panel is a cost-effective system in terms of both the quality of construction and the economy. Anti-seismic constructions can be built with additional reduction of heat dispersion and noise attenuation. In this study the structural system is composed of a factory produced corrugated panel of polystyrene covered on both sides by an electro-welded zinc coated mesh of galvanized steel and shotcreted concrete poured to build the vertical structural walls. This system allows economic savings compared to the traditional systems; however, deformability of the base connections can alter significantly the structural behaviour and seismic response.

Abstract

Fast construction of structural walls made of reinforced concrete for buildings or industrial warehouses in single panel is a cost-effective system in terms of both the quality of construction and the economy. Anti-seismic constructions can be built with additional reduction of heat dispersion and noise attenuation. In this study the structural system is composed of a factory produced corrugated panel of polystyrene covered on both sides by an electro-welded zinc coated mesh of galvanized steel and shotcreted concrete poured to build the vertical structural walls. This system allows economic savings compared to the traditional systems; however, deformability of the base connections can alter significantly the structural behaviour and seismic response. This study deals with both experimental tests on a real scale structure and numerical simulations, with the goal to provide an efficient formulation to model the deformability of base connections in such sandwich concrete structures, while the materials are modelled either linear elastic or nonlinear.
