Abstract

Abstract

It is researched 4 unbonded pos-t tensioned precast concrete beams under reversed cyclic loading. In this study there are some parameters that are taken into account, such as PT eccentric position, PT anchor length and initial pos-t tensioning load. Experiment shows that these beams used unbonded pos-t tensioned tendon have desirable seismic characteristics such as a sel-f centering capability and an ability to undergo large nonlinear displacements with little damage. Some seismic behaviors such as resilience, ductility, energy dissipation etc are analyzed. The objective of this test is to develop guidelines for precast structure in regions of earthquake zone.
- post-tensioned unbonded precast concrete beams,
- reversed cyclic loading,
- self-centering,
- energy dissipation seismic behavior,
