Effect of Prestressing on Plastic Behaviour of Reinforced Concrete Frame

Subject of this paper is to analyze the effect of prestressing on the plastic behavior of reinforced concrete frame. One-story frame with span of 15m was designed as reinforced concrete structure as well as prestressed concrete structure. For each frame nonlinear model was constructed and nonlinear time-history analysis was conducted using seven ground motions records selected according to EN 1998-1. Results of nonlinear analysis for both frames were analyzed and compared and conclusions regard the effect of prestressing on plastic behavior of reinforced frame are presented in this paper.
