However, in 1995 Kobe EQ, premature collapses such as the first-story local sway collapse mechanism, or brittle fractures in the welding joints were widely observed in low-to-middle rise steel moment frames due to damage concentration. The damage (plastic strain energy) concentration to a specific story or the inter-story damage distribution phenomena are studied through dynamic elasto-plastic response analyses using trial modeling of low-rise (3 stories) steel moment frames. The results are summarized and discussed in terms of the story-drift responses, the cumulative rotation capacities of plastic hinges, or the plastic-energy absorbed quantities and its concentration patterns.
