in this paper, efforts are made to compare the safety of steel moment resistant frames designed according to different editions of the iranian code of practice for seismic resistant design of buildings. also, failure risk of a low and medium height frame which designed for high and low seismicity regions according to three editions of the code are evaluated. first, the testing cases were design...

This article presents the results of a seismic risk assessment of the bridge network in Charleston, South Carolina and the surrounding counties to support emergency planning efforts, and for prioritization of bridge retrofit. This study includes an inventory analysis of the approximately 375 bridges in the Charleston area, and convolution of the seismic hazard with fragility curves analytically...

The concepts of seismic resilience need a unified terminology and a common reference frame for quantitative evaluation of such resilience. The evaluation can be based on non-dimensional analytical functions related to loss variation within a specified “recovery period”. The path to recovery usually depends on available resources and may take different shapes which can be estimated by proper rec...

Industrial equipments and systems can suffer structural damage when hit by earthquakes, so that accidental scenarios as fire, explosion and dispersion of toxic substances can take place. As a result, overall damage to people, environment and properties increases. The present paper deals with seismic risk analysis of industrial facilities where atmospheric storage tanks (anchored or unanchored t...

The concept of seismic resilience needs a quantitative evaluation. The evaluation suggested in this paper is based on nondimensional analytical functions related to variations of losses within a specified “recovery period”. The resilience refers to both direct and indirect losses. The path to recovery usually depends on available resources and may take different shapes, which can be estimated b...

The purpose of this research is to set forth the basis for developing fragility curves that can be used in various ways as part of a seismic vulnerability analysis methodology for highway bridges. To develop a set of fragility curves for various damage states for a specific bridge, the notion of adjusting “Standard Bridge” fragility curves for sitespecific effects is adopted. Only three sources...

Abstract The seismic vulnerability of bridges may be reduced by the application Geotechnical Seismic Isolation (GSI) below foundations columns and abutments. However, role GSI on response has been limitedly examined in literature. Therefore, this research conducted to study effect applying address aforementioned gap knowledge. Advanced nonlinear dynamic three-dimensional finite element analyses...

The objectives of this task are to conduct research on seismic hazards, and provide relevant input on the expected levels of these hazards to other tasks. Other tasks requiring this input include those dealing with inventory, fragility curves, rehabilitation strategies and demonstration projects. The corresponding input is provided in various formats depending on the intended use: as peak groun...
