- •
Uncertainty propagation in the alternate path mechanism of RC structures is studied using global variance-based sensitivity analysis.
- •
Compressive arching action significantly influences uncertainty propagation.
- •
Alternate path mechanism is found to be a strength-sensitive problem.
- •
Use of displacement-based element formulation is not reliable when plastification is extreme.
- •
Structural idealization significantly reduces computational costs in probabilistic analysis.
