A hybrid concrete wall is made up of a traditional reinforced with post-tensioned technology. Recent research has shown that (PT) shear walls have wide range advantages when it comes to resisting lateral forces and moments caused by earthquake loading. To explore the PT behavior subjected seismic load, models were augmented various material models, including KCC, CDP, Winfrith for 2D under push...

A buckling solution and a non-linear post buckling solution were employed for the wrinkling analysis of a tensioned Kapton square membrane. The buckling solution with significantly reduced bending stiffness creates localized buckling modes accounting for the wrinkle formation in the membrane. The non-linear post buckling solution with an updated Lagrangian scheme describes the detailed wrinkle ...
