- Abstract
- The main objective of the research is to determine the seismic hazard associated with reinforced concrete structures in the eastern United States. The structures considered are medium to high rise, and are designed without consideration of seismic loading. Damage is quantified as an index which can be used to determine whether the structure is repairable, severely damaged, or collapsed. The damage of the structures is calculated using comprehensive inelastic dynamic analysis. For the purpose of the study, a Monte Carlo simulation approach has been chosen with simulated earthquake motion developed from spectral characteristics of earthquake typical to eastern North America. The study considered three similar test structures to determine the damage level associated with different types of designs. Two of the structures considered were frame type structures, one structure was a 'weak beam' design and the other was a 'weak column' design. Additionally, a coupled frame shear wall structure was considered to determine the effect of the shear wall on the resulting damage index.
