Nonlinear Analysis of Reinforced Concrete Elements and Joints

Nonlinear analysis of reinforced concrete joints plays a pivotal role in understanding and enhancing the structural behavior against earthquakes. These joints are critical elements within concrete structures, connecting beams, columns, and other structural members.

Through nonlinear analysis, engineers can model the complex behavior of these joints under seismic loading, considering factors such as material nonlinearity, joint geometry, and reinforcement detailing. We model both the concrete and steel bars using steel-layered or steel-bars models.
