Developments of steel-concrete-steel sandwich composite structures with novel EC connectors: Members
Abstract This paper developed new steel-concrete-steel (SCS) sandwich composite structures using novel enhanced C-channels (ECs) for civil engineering infrastructures as shear walls, bridge decks, and protective structures. Their structural behaviours have been studied through a series of tests from the component to structural member level. Push-out tests on ECs, two-point loading tests on SCS sandwich beams with ECs (SCSSB-ECs), axial compression tests on SCS sandwich walls with ECs (SCSSW-ECs), in-plane cyclic shear tests and out-of-plane punching shear tests on SCSSW-ECs were carried out to investigate the shear behaviour of ECs, flexural and shear behaviour of SCSSB-ECs, compression behaviour, in-plane seismic behaviour, and out-of-plane punching shear behaviour of SCSSW-ECs, respectively. These studies offered comprehensive information of structural behaviours of SCS sandwich structural members with ECs. Including these experimental studies, corresponding prediction equations were also proposed for ultimate shear resistance and shear-slip behaviour of ECs, flexural and shear resistances of SCSSB-ECs, axial compression resistance, in-plane lateral shear resistance, and out-of-plane punching shear resistance of SCSSW-ECs. Through validations against reported test results, accuracies of these developed prediction equations were confirmed.
