An innovative sandwich wall panels as structural load-bearing elements have been presented. Besides the conventional configuration of sandwich panel, this new panel system has some distinctive characteristics including core column reinforced by spiral stirrup along the panel cross-section with spacing 650mm, foamed concrete as insulation layer, self-compacting concrete used in external layers. Furthermore, to improve the global strength and stiffness of panel, 3D steel wire system which is composed by two vertical steel wire meshes connected by horizontally short steel bar has been uniquely employed in concrete layer. An experimental campaign has been carried out to investigate the seismic behavior of this new panel system. According to the analysis of load-bearing capacity, hysteretic behavior, skeleton curves and stiffness degradation, conclusions could be drawn that the new prefabricated concrete sandwich wall system has comparable performance with traditional concrete solid wall.
