Seismic Evaluation of Steel Moment Frame Buildings Designed Using Different -Values
Publication: Journal of Structural Engineering
Volume 132, Issue 9
Abstract
Current seismic design procedures, which permit the estimation of inelastic deformation capacity of lateral force resisting systems, have been questioned since no rationality exists for determining the values of tabulated in seismic design codes. This study focuses on the seismic behavior of three-, nine-, and 20-story steel moment resisting frame (MRF) structures designed using different factors (8, 9, 10, 11, and 12). A total of 30 different structures were subjected to 20 ground motions representing the hazard level equal to a 2% probability of being exceeded in 50 years (2% in 50 years) for a detailed case study. Then, a reliability-based performance evaluation procedure, which provides a degree of confidence for satisfying the collapse prevention (CP) performance objective, was applied to model buildings to assess the effect of the factor variations. The results show that the current factors provide conservative designs for the three- and nine-story buildings for achieving the CP performance objective. However, the 20-story buildings designed with different factors without the minimum spectral acceleration bound on prescribed in the 2000 International Building Code show a low level of confidence for achieving CP performance.
