Seismic reliability of low-rise nonsymmetric woodframe buildings

Abstract

Seismic responses and reliability of a one-story L-shaped woodframe building tested at the CSIRO Structures Laboratory and a hypothetical two-story L-shaped building based on the test house were investigated using a three-dimensional hysteretic frame model under bidirectional ground motions. Parameters of the degrading and pinching hysteresis used for the shear walls were identified from whole house testing. The SAC ground motions for the Los Angeles area were used and the effects of torsion, bidirectional excitations, the variability in ground motion, structural modeling, collapse capacity, and vibration period were investigated. It was found that uncertainties due to ground motion and stru..
