Story Building

Inelastic response of one-story building systems with eccentricity is investigated based on linear static and nonlinear dynamic analyses using asymmetric-plan systems simultaneously subjected to strong earthquake ground motions in the x- and y-directions. Inelastic story drift ratios in the x- and y-directions are evaluated considering shear and torsional strength capacity and the corresponding shear force and torsional moment acting in each direction of asymmetric-plan system. Response analysis of one-story systems with one-axis plan asymmetry and varying parameters such as uncoupled lateral vibration period, torsion-to-lateral frequency ratio, rigidity and strength eccentricities, and shear and torsional strength capacity ratio is carried out and compared with those of corresponding one-story symmetric systems. In addition, inelastic response of one-story building systems with two-axes eccentricity including a L-shape asymmetric-plan system is also investigated.

Earthquake Ground Motions

We present correction factors that may be applied to the ground motion prediction relations of Abrahamson and Silva, Boore and Atkinson, Campbell and Bozorgnia, and Chiou and Youngs (all in this volume) to model the azimuthally varying distribution of the GMRotI50 component of ground motion (commonly called “directivity”) around earthquakes. Our correction factors may be used for planar or nonplanar faults having any dip or slip rake (faulting mechanism). Our correction factors predict directivity-induced variations of spectral acceleration that are roughly half of the strike-slip variations predicted by Somerville et. al. (1997), and use of our factors reduces record-to-record sigma by about 2–20% at 5 sec or greater period.
