Structural System Parameter Selection Based on Collapse Potential of Buildings in Earthquakes
Publication: Journal of Structural Engineering
Volume 136, Issue 8
Abstract
This paper attempts to provide insight into the sensitivity of the collapse capacity of moment-resisting frame and shear wall structures to variation in basic structural parameters, and the choice of an appropriate ground motion intensity measure, based on probabilistic estimation of the collapse capacity of a structural system. The effects of fundamental period and base shear strength and of deformation and deterioration properties of structural components on the collapse capacity of frame and wall structures are quantified. It is shown that the collapse potential of moment-resisting frames is highly sensitive to the ratio of column to beam strength; increasing this parameter from 1.2 to 2.4 will increase the median of collapse capacity by up to 90%. Using a scalar ground motion intensity measure for estimating the collapse capacity can lead to underestimation of median collapse capacity by up to 50%, compared to using a vector-valued intensity measure. The provided information can be used to assist in the selection of a suitable structural system and associated parameters in design for collapse safety. Closed-form solutions are formulated using a database of collapse fragility curves developed for the sensitivity study. Application of these closed-form solutions for design decision making is illustrated through a comprehensive example.

This research was supported by the NSF sponsored Pacific Earthquake Engineering Research (PEER) Center, and was carried out at Stanford University’s John A. Blume Earthquake Engineering Center as part of a comprehensive effort to develop basic concepts for PBEE and supporting data on seismic demands and capacities. The support is gratefully acknowledged.

This publication is dedicated to Professor Franz Ziegler of the Technical University of Vienna, Austria, at the occasion of his 70th birthday. Professor Ziegler has been a good friend of the second writer since the latter spent three months at the Technical University of Vienna in Spring 1995. It was a great pleasure and rewarding experience to have spent a sabbatical leave at Professor Ziegler’s institute and have had the opportunity to discuss then, and many times since, structural dynamics with such an eminent leader in applied mechanics. Beste Glückwünsche zum Geburtstag, lieber Franz.NSF
