Parametric Study on the Effect on Seismic Demands of Structural Configuration, Proportioning and Modeling 

Principal Investigator: Helmut Krawinkler

    The objective of this task is to develop concepts and information needed to identify and predict local and global seismic demand parameters which have a significant effect on the seismic response of steel moment resisting frames. Several of the specific topics to be investigated in this task include: 

o Evaluating the effect on seismic demands of locating plastic deformations in beams at the face of a connection, in beams away from the face of the connection, in panel zones, and in the columns of steel moment-resisting frames. 

o Assessing the influence of configuration, redundancy and proportioning. 

o Assessing the influence of various modeling approaches and refinements. 

o Developing simplified procedures for estimation of local demands from limited information on the strength and stiffness of the structure and the spectral characteristics of the anticipated ground motion.
