Topical Investigations on System Performance
Task Number: 5.4.5
Parametric Study on the Effects on Seismic Demands of Ground Motion Intensity and Dynamic Characteristics
Principal Investigator: Greg MacRae
The objectives of this task are to assess the effects of different ground motion characteristics on the local and global seismic demands for steel moment resisting frame structures. Specific issues to be addressed include:
1. The effect of increasing the intensity of ground motions due to earthquakes with more or less probability of occurrence.
2. The effects of ground motions that have a narrow-banded high energy content around a predominant period, such as near-field ground motions and motions occurring on soft soils.
3. The effects of simultaneously applied (multiple) components of ground motions, including those applied along the vertical axis.
The detailed breakdown of the technical activities in this task are provided in the workstatement available here.
