Experimental Seismic Performance of Self-Control Energy Dissipation UPPC Frame

  • 35 Accesses

Abstract

A self-control energy dissipation unbonded partially prestressed concrete (UPPC) frame refers to the rational setting of self-control energy dissipation components in the UPPC frame, which aims at reducing the stress of unbonded prestressed reinforcement during severe earthquakes. Besides, part of the prestress in the beam during that period can be released to form a beam-hinge energy dissipation mechanism and strong column-weak beam ductility frame. In this paper, the experimental study of two frames (UPPC frame and self-control energy dissipation UPPC frame) under low cyclic loading demonstrates that the self-control energy dissipation UPPC frame of this experiment presents a better energy dissipation capacity and thus can form a beam-hinge mechanism.
