dc.description.abstract | Recent, worldwide earthquakes have highlighted the destructive potential of near-fault, pulselike ground motions caused by forward directivity. This study investigates the fracture risk of welded steel column splices (WCSs) in near-fault regions, especially quantifying the pulse effects on WCS stress demands through incremental dynamic analysis (IDA). For this purpose, two case-study nonlinear steel moment frame models are developed and subjected to a set of pulse-like ground motions with varying pulse periods and a suite of ordinary (i.e., non-pulse-like) ground motions, respectively. Results of IDA are then combined with near-source probabilistic seismic hazard analysis (NS-PSHA) to assess fracture risk. Findings from the study suggest that WCSs in pre-Northridge steel frames may be highly susceptible to fracture due to directivity-induced pulse-like ground motions. | - |
