Midas Civil pushover and performance evaluation is the static incremental seismic workflow that applies lateral loading, traces nonlinear capacity, and evaluates structural performance against target or performance-point criteria.
How It Works
The manual treats pushover as an incremental nonlinear static analysis. It includes load-control and displacement-control options, applied lateral load patterns, nonlinear element or hinge properties, performance point estimation, and a seismic performance evaluation workflow.
Pushover is not just a solver setting. It packages model idealization, hinge definitions, load pattern selection, control DOF selection, capacity-curve extraction, and acceptance criteria.
Solver Development Notes
A custom solver needs a repeatable way to define control nodes, displacement targets, load patterns, and stopping criteria.
Plastic hinge output should expose yield state, demand/capacity ratios, and member-level response in addition to global displacements.
Verification should compare capacity curves, hinge sequence, base shear, and target displacement against a reference solver.
Test harnesses should include both load-controlled and displacement-controlled paths.
