Comparison of reliability- and design-based code calibrations

• Code calibration procedures are compared for accuracy and computational efficiency. Reliability-based code calibrations deemed more accurate. Design-based computationally significantly faster. beneficial format optimization. Some of the early probabilistic minimized an error term defined as difference between optimal or target design resulting with trial partial factors format. In contrast to these design-based calibrations, in recent years, was terms a reliability deviation. Aiming at minimizing societal costs, reliability-based probably provide accurate results than however cost lower The long duration impedes repeated which needed development profound understanding it.
