Investigating the Reliability of Ground Motion Intensity Measures

Advances in Civil Engineering, Volume 2024, Issue 1, 2024.
The uncertainty and unreliability in the probabilistic seismic demand models (PSDMs) can be addressed in the framework of performance‐based earthquake engineering (PBEE). Some characteristics have been introduced and extensively investigated in the earthquake engineering literature for appropriateness (i.e., optimality) of various intensity measures ...
