Seismic performance of a steel moment-resisting frame subject to strength and ductility uncertainty

Application of endurance time method in performance-based optimum design of structures

“…Liel et al [5] and also Ibarra and Krawinkler [6] showed that uncertainties in structural parameters can have more significant effects on collapse performance of structures. A more detailed review of the recent literature on reliability assessment can be found in a work by Kazantzi et al [7]. They examined the effects of the model parameter uncertainties on the seismic performance of a steel frame, revealing that the consideration of model parameter uncertainties can be safely ignored for global behavior of the frame.…”

More adequate seismic design force pattern for yielding structures considering structural and ground motion uncertainties effects

“…On the other hand, Haukaas and Kiureghian and Kwon and Elnashai showed that the nonlinear response of building structures would be more sensitive to changes in dynamic properties of structural models and characteristics of future earthquake ground motions when compared with the elastic response of the corresponding structures. In another investigation, the influence of strength and ductility uncertainty was examined by Kazantzi et al and concluded that disregarding the model parameter uncertainties may result in an underestimation of fragility for local damage‐states. In one of the more recent study, Hajirasouliha et al investigated the effect of uncertainty on seismic performance of optimum concentrically braced frames subjected to 15 synthetic ground motions.…”

A Next Generation Scalar Intensity Measure for Analytical Vulnerability Studies

“…Figure 1 depicts a 2-D idealization of the East-West MRF along with the beam and column section sizes. A detailed description of the MRF geometry, design and modeling can be found in Lignos et al [18] and Kazantzi et al [10]. …”

“…On that premise, and considering the recent findings suggesting the ground motion duration to affect the collapse capacity of both non ductile and ductile structures [9], we will propose in this study a new scalar IM that combines the geometric mean IM concept with the significant duration property of the ground motions. The testbed for the present study will be a single contemporary capacity-designed midrise steel moment-resisting frame (MRF) [10]. Nevertheless, it is believed the results being applicable to collapse vulnerability studies that involve either higher numbers of stories or even a class of buildings, but this is up to upcoming ongoing research to prove.…”
