Influence of intense ground motion on p-delta effect amplification

High intensity ground motion can cause significant deformations, which is the basis for additional second-order responses. This analysis uses two recorded ground motions for historical large earthquakes (Kocaeli and Tohoku), a sinusoidal curve, and a simulated ground motion based on the 1906 San Francisco earthquake. These ground motions are applied to material elastic and material plastic version of two benchmark structures developed for the Los Angeles region and the overturning moment and displacements are recorded. The responses are highly dependent on the ground motions, and there is some amplification due to the second-order analysis. The 20-story benchmark structure had more of a second-order amplification, but the moment amplification was under 10% and the displacement amplification was around 5%.
