Abstract Simulated ground motions from the M W 6·7 Northridge earthquake and a simulated M W 7·0 Elysian Park event are generated over a large grid of sites and used as input to mathematical models of six‐storey and 20‐storey steel‐frame buildings. Purpose of the study is to quantify effects of strong near‐source ground motion on frame buildings of different height and strength (UBC vs. Japanese design) and with welded connections prone to fracture. Best performance is achieved by the six‐storey building which meets the stronger Japanese design provisions. The detrimental effect of connection fracture is significant, especially for the larger earthquake. © 1998 John Wiley & Sons, Ltd.
