Seismic fragility assessment of building-type structures in oil refineries

Spectral evaluation of seismic fragility of structures

ABSTRACT: An approach for assessing the seismic fragility of inelastic structures is presented. In this approach, the structural response, which is evaluated from response spectra with an associated probability distribution, is compared with the performance limits states to assess fragility. Formulas that provide the probability distribution of spectral ordinates are developed based on the cros...

assessment of the efficiency of s.p.g.c refineries using network dea

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

Seismic Response of Building Structures with Sliding Non-structural Elements

Interaction between a structure under base excitation and heavy non-structural elements that it supports is significant in the seismic analysis and design of the structure. Heavy non-structural elements may slide/rock under base excitation, and this dynamic action affects the seismic behavior of the supporting structure. Hence, in this study, a numerical model was presented to describe the seis...

Seismic Fragility Assessment of Steel SMRF Structures under Various Types of Near Fault Forward Directivity Ground Motions

In this paper, the seismic collapse probability of special steel moment-resisting frame (SSMRF) structures under near fault pulse-like and far fault ordinary ground motions is evaluated through fragility analysis. For this purpose, five sample frames with 3 to 15 stories are designed and imposed to the ground motion excitations with different characteristics. Fragility curves are derived for th...
