Effects of Prestressing Magnitude and Position on Seismic Performance of Unbonded Prestressed Concrete Beams

Buildings
To study the effects of the jacking stress level, height and strength ratio of the prestress tendons (λ) on the seismic performance of unbonded prestressed concrete (UPC) beams, six UPC beams and one reinforced concrete (RC) beam were tested under cyclic
