Abstract
In this research, a new sandwich wall system has been presented as structural elements which has unique structural configuration such as 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 which is significantly different from traditional sandwich wall. Seismic performance of sandwich walls with planar or 3D steel wire system is studied by low cycle repeated load test. According to the analysis of hysteresis performance and skeleton curves, this sandwich wall exhibits good seismic performance and crack resistance. Specimen with 3D steel wire shows better seismic behavior with higher strength and ductility.
