Abstract
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 and two layers of concrete on both sides. In this paper, attention
is focused on the experimental measurements of the seismic response of 3D wall
panels surrounded by a steel bending frame. The approach of quasi-static cyclic
loading is employed using horizontal actuators to the combined system. The
vertical, lateral and horizontal displacements are measured by LVDT equipment.
The failure mechanism of 3D wall panels is described in detail. The evaluation
of strength and stiffness degradation of the whole system is presented based on
the envelope force-displacement curve of actual specimens under cyclic loads.
The results of the current study are shown in the form of ductility factors,
hysteresis loops and load-displacement envelope curves. The comparison
between the ductility of sole steel frames, 3D shear walls and the combined
system as the main theme of the current research is presented. Finally, this work
clarifies the benefits of using 3D wall panels as a strengthening method for
existing steel frame buildings and confirms the feasibility resistance of such
combined systems.
Keywords: 3D-panels, combined system, cyclic loading.
