文摘
Insulating Concrete Form (ICF) includes permanent formworks, most commonly expanded polystyrene foam. Insulating Concrete Forms create a formwork for concrete that stays in place as permanent building insulation. Structures usually experience plastic deformations during major earthquakes; however, because of complexity of performing non-linear analysis, codes consider effects of inelastic behavior through reduction factors (R) and allow linear analysis instead. Reduction factor has not been presented for Screen-Grid ICF (SGICF) wall system until now. In this research, reduction factors due to ductility of SGICF wall systems are determined by non-linear static analysis (Pushover) and Concrete Damaged Plasticity constitutive model (CDP) in ABAQUS 6.12. Then the results are compared to those of the experimental model. Results from this research show that such structural system, if used in high seismic risk zones, has an acceptable ductility.
