Use of plastic hinge model in nonlinear pushover analysis of a pile / Jiunn-Shyang Chiou in Journal of geotechnical and geoenvironmental engineering, Vol. 135 N° 9 (Septembre 2009)

When the pile section enters the plastic state, the plastic hinge method is usually adopted to model its postyielding flexural behavior. The propagation of the plastic zone in a pile can be traced using a series of plastic hinges distributed along the pile that is embedded in the soil. This study proposes a proper model for arranging the distributed plastic hinges along the depths of the pile that are prone to yielding. A modified definition of plastic curvature is proposed herein in order to correctly simulate the nonlinear flexural behavior of a pile. Examples are presented to show the effectiveness of the proposed model.
