The case study building experienced moment connection fractures and has instructure recorded response. Correlative analyses are performed using a probability approach to describe the connection rotational capacities. The Northridge calibrated model is then subjected to other scenario earthquake records. The main points include: -Northridge connection damage can be reasonably simulated using models that idealize the rotation capacities as random variables, -Many of the connection fractures occurred from beam moment demands that were less than the beam yield moments, -Vertical earthquake excitation and gravity loads did not play a major role in the connection fractures, -The damaged building can withstand another Northridge intensity quake, -Near-source ground motions from great quakes have the potential to collapse the building with pre-Northridge type connection details, and -Connection rotation capacity can make the difference between building survival or collapse during severe quakes. |
