Abstract:This paper reports on the experimentally and analytically observed behavior of unbounded post-tensioned precast concrete walls under static monotonic and cyclic lateral loads. Results show that the limit states that characterize that lateral load behavior of the walls occur as anticipated in the design of the walls and at force and drift levels predicted by the analytical model, except that the experimentally observed drift capacity exceeds the drift capacity predicted by the analytical model. Cyclic lateral load results how that unbonded post-tensioned precast walls can undergo significant nonlinear lateral drift without significant damage, and can maintain their ability to self-center, thus eliminating residual lateral drift.
