A reliability-based methodology for capacity design factors for seismic resistant steel buildings.
Capacity design principles are employed in structural design codes to help ensure ductile response and energy dissipation in seismic resisting systems. Capacity design requires that the strengths of certain components are sufficient to resist forces induced by other components of the system that are specifically designed to sustain large inelastic deformations. While the basic concept of capacity design is straightforward, its implementation requires consideration of many factors related to the variability in component strengths, deformation demands and overall inelastic system response. Despite recent progress in developing consistent capacity design factors, the focus has mainly been at the component level and there are still inconsistencies in the way that capacity design factors are established for different seismic force resisting systems. The goal of this research is to develop a reliability-based methodology to decide upon appropriate capacity design factors such that they create consistent system reliability between different seismic force resisting systems.
