抄録

Three prestressed concrete portal frames (span: 2.6m, height: 0.9m) were loaded horizontally. Resistance against lateral force, ductility, and dynamic behaviours of these frames were examined. As the results of the experiment, the following facts were clarified: (i) Ultimate design method is applicable for prestressed concrete portal frames, (ii) ample ductility is guaranteed, (iii) deterioration of deformation characteristics under repeated loading is not considerable, (iv) increment of period of natural vibration and increse of fraction of critical damping in accordance with increase of load are small.
