3D wall panels are used in the construction of exterior and interior bearing and non-load bearing walls and floors of building of all types of construction. This system consists of a welded wire space frame integrated with a polystyrene insulation core. The wall panel is placed in position and wythes of concrete are applied to both sides. This combination produces a truss behavior, which provides rigidity and shear terms for full composite behavior. The present paper investigates the performance of such resistance elements against shear loading. A total of six welded wire shotcreted sandwich panels are subjected to seismic type lateral forces. Two different sizes of wall panels are tested with identical materials. The applied methods are based on experimental investigation. The failure mechanism is studied in details. Results of the current investigation are presented in the form of load-deflection plots and the ductility factor is calculated for comparison with traditional reinforced concrete shear walls.
