A dynamic analysis method that tracks the exact sequence of loads, displacements, or accelerations applied to a structure over time. Instead of looking at peak static loads, engineers use these transient records to see how a system responds to sudden shocks, vibrations, or seismic events. It provides a step-by-step mathematical picture of structural behavior.
Run the seismic time history through the FEA model to see if the pipe supports yield during the first five seconds.
