Nonlinear finite element analysis of prestressed concrete members using ADINA

A prestressed concrete (PC) column and a precast segmental PC beam are analyzed using ADINA. Two dimensional finite element model is employed with material nonlinearities (concrete cracking/crushing and rebar plasticity) and geometrical nonlinearities (large displacement and contact/separation between the segments). The load-displacement relationship, the concrete cracking/crushing process, the load-strain relationship, and the gap opening/closing are in good agreement with those in the tests.
