ABSTRACT: Precast concrete structures with hinge connection are ideal constructions for factories, which need open spaces without columns. In industial zones, precast concrete structures are prefered because of their economic and rapid production. It is a fact that a large part of the industrial regions are located on high risk earthquake zones. In the recent earthquakes, large numbers of people have died or heavily injured in the complete collapse of buildings constructed with reinforced and precast concrete structures. In the design of precast concrete structures, frames are generally analyzed in two dimensions. It is known that infill walls increase global stiffness and strength of the structure. But generally infill masonry walls are not taken into account in the evaluation of the lateral load capacity of precast concrete structures. The infill masonry walls increase the stiffness and lateral capacity of the frame structures. Although, infill masonry walls increase these parameters, infill walls are generally not taken into consideration in the lateral load capacity of precast concrete structures. The objective of this study is to investigate the effects of infill masonry walls on structural performance of precast concrete structures. In the analyses, diagonal strut model is adopted for modeling masonry infill walls. Collapse mechanism and load deformation relationship of infilled precast concrete structures are compared and results are given in figures. A sample precast structure has been selected to investigate the effect of infill walls on the overall structural behavior and on the lateral load capacity of precast concrete structure with hinge.
