This paper studies the effects of uplift in spread foundations and yielding of underlying soils on sectional force induced in bridge piers subjected to pulse-like ground motions using a macro-element model developed by PWRI. Sinusoidal pulse, which simulated pulse-like ground motions, was used. As a result, it was found that degree of stress reduction effects vary depending on pulse period characteristics as well as peak acceleration of pulse-like ground motions.
