EFFECT OF SHEAR FORCES ON MONOPANEL BEAM SPECIMENS

Abstract

A monopanel system is a new building material system of ferrocement that consists of two thin ferrocement block-like faces and a thick layer of low strength, density and cost polystyrene foam insulation between them as a core. The simple structural idealization of a monopanel system is that the core provides shear transfer between the faces that provide flexural and compression resistance. Transverse trusses made of steel bars having a diameter of 3.2 mm, which serve as tie reinforcement to prevent the thin ferrocement skins from local buckling, have been used in the present work. These transfer system consist of two longitudinal bars connected by inclined steel bar forming trusses shape making an angle equals to 60o with the longitudinal bars. The main object of this research is to present an experimental investigation on the behavior and load carrying capacity of monopanel beams. The experimental work includes testing nine monopanel beams, and has been investigated the effect of a different depths of monopanel beams on the behavior and the ultimate load capacity. Also comparison of these results with the ACI code formulations have been made.
