An Experimental and Analytical Study on perpendicular to plane Flexural behavior of New Prefabricated Wall Made by Extruded Polystyrene

Abstract

Nowadays softening of non-structural components as well as applying dry-wall systems are one of the efficacious measures to safe constructions against earthquakes. Using rigid and heavy non-structural elements, increase earthquake force and its destructive effects on the structure. Therefore, using flexible and light material in non-structural elements is one of the effective solutions to build light and safe structures against earthquakes. In this study, an experimental and analytical investigation on the behaviour of a new pre-fabricated wall made by extruded polystyrene, gypsum board and cement board has been studied through a comparative analysis that the following conclusions can be drawn. C-C Panels have 35% More resistance and G-G Panels have 37% more Plasticity. Thickness has positive effects on resistance and plasticity. Panels with thickness of 12.5cm have 37% more resistance and 21% more plasticity in comparison with panels with thickness of 7.5 cm.
