| Abstract | ||
| A monopanel system is a new building material system of ferrocement that consists of two thin ferrocement block-like faces and thick layer of low strength, density and cost polystyrene foam insulation between them as a core. The simple structure idealization of monopanel system is that the core provides shear transfer between the faces that provide flexural resistance. Transverse trusses made of steel bars having diameter of (3.5) mm which serve as tie reinforcement to prevent the thin ferrocement layer from local buckling, have been used in this research and they are connected by inclined steel bar forming trusses shape making an angle equal to 60° with the longitudinal bars. The core material can be made of low cost materials such as aerated concrete, expanded polystyrene concrete, polystyrene foam, which is used in the present research work. Monopanel systems can be constructed on site or produced as precast units with very accurate and controlled dimensions. They can be used as walls, slabs, beams, columns and other types of similar construction. Such panels should therefore offer an excellent structural system not only for low cost housing but also for low-rise buildings (up to three stories) such as residential units. The main object of this research is to present an experimental investigation on the behavior and load carrying capacity of monopanel columns. The experimental work includes testing nine monopanel columns, and has been investigated the effect of a different depths of monopanel columns on the behavior and the ultimate load capacity. Also comparisons of these results with the ACI-318M-08 code formulations have been made. | ||
