    Abstract

    Results from small-scale models of eight high-strength prestressed concrete frames, tested under various displacement histories simulating earthquake forces are presented. The primary curves (horizontal force-displacement relationships) and the hysteretic loops are determined experimentally. Concrete strength is approximately between 50 and 60 mPa, and effective prestress is 50% of the ultimate strength of the prestressing steel. It is found that the effect of displacement history on the mechanical behavior is significant because the entire shape of the hysteretic loops is different and the prestressed concrete frames made of high-strength concrete with a slump of 25 cm may have at least a ductility factor of 8.0.
