This paper presents a conceptual framework to define seismic resilience of communities and quantitative measures that can be useful for coordinated research effort focusing on enhancing this resilience. relies the complementary resilience: “Reduced failure probabilities,” consequences from failures,” time recovery.” The also includes “ends” robustness rapidity, “means” resourcefulness redundancy, integrates those into four dimensions community resilience—technical, organizational, social,...

Abstract This paper presents a comprehensive model to quantify disaster resilience of systems that is defined as the capability sustain functionality and recover from losses generated by extreme events. The combines loss estimation recovery models can be applied critical facilities (e.g. hospitals, military buildings, etc.), well utility lifelines electric power systems, transportation networks, water etc.) are crucial response processes, decisions policies. Current research trend leads...

This paper explores the operational and physical resilience of acute care facilities, recognizing that key dimension facilities is not a simple engineering unit. Quantification first approached from broader societal context, which subproblem formulated, that, to operate, hospitals depend intricately on performance their infrastructure (from integrity structural systems nonstructural systems, lifelines, components, equipment). relates probability exceeding floor accelerations interstory...

This paper describes the prototype design, specimen experimental setup, and results of three light-gauge steel plate shear wall concepts. Prototype walls are designed as seismic retrofits for a hospital structure in an area high seismicity, emphasis is placed on minimizing their impact existing framing. Three single-story test specimens using these prototypes basis, two with flat infill plates (thicknesses 0.9mm) third corrugated (thickness 0.7mm). Connection to boundary frames achieved...

A revised procedure for the design of steel plate shear walls is proposed. In this thickness infill found using equations that are derived from plastic analysis strip model, which an accepted model representation walls. Comparisons experimentally obtained ultimate strengths and those predicted by given reasonable agreement observed. Fundamental collapse mechanisms several, more complex, wall configurations also given. Additionally, existing codified reviewed a section could lead to designs...

The performance of concentrically braced steel frames and moment resisting during the January 17, 1994, Northridge, California, earthquake is examined. Most observations made reconnaissance visits confirmed current knowledge on inelastic response these structural systems. This permits anticipation proper seismic behavior for buildings designed according to provisions that have been recently introduced in Canadian building code standard structures. In some cases, however, observed damage...

This paper presents results of an experimental investigation specially detailed ductile perforated steel plate shear walls (SPSWs) designed to accommodate utility passage, and having anchor beams with reduced beam sections connections. Single-story, single-bay SPSW frames are subjected quasi-static cyclic loading up their maximum strength displacement capacity. The tested specimens also had low yield infill panels. Two make allowances for penetration the panel by utilities. first, multiple...

The concept of disaster resilience has received considerable attention in recent years and is increasingly used as an approach for understanding the dynamic response to natural disasters. In this paper, a new performance index measuring functionality gas distribution network been proposed, which includes restoration phase evaluate entire network. can also be any type or artificial hazard, might lead disruption system. municipalities Introdacqua Sulmona, two small towns center Italy that were...

SUMMARY A resilience index is used to quantify preventive measures, emergency and restoration measures of complex systems, such as physical infrastructures, when they are subjected natural disasters like earthquakes, hurricanes, floods, etc. Interdependencies among these systems can generate cascading failures or amplification effects, which also affect the right after an extreme event a reduction index. In this article, method proposed evaluate infrastructure region affected by disaster...

A large proportion of North America's older building inventory is unreinforced masonry (URM), constructed in the absence mandatory earthquake design requirements, and unquestionably recognized as type construction most vulnerable to earthquakes. Awareness this seismic hazard relatively new eastern America. In addition, nature risk other engineering constraints there shed a different perspective on problem. This state‐of‐the‐art paper performance URM buildings summarizes knowledge that has...

This paper presents the development and experimental validation of a multizard bridge pier concept, i.e., system capable providing an adequate level protection against collapse under seismic blast loading (but not acting simultaneously). A multicolumn pier-bent with concrete-filled steel tube (CFST) columns is proposed adequacy this experimentally investigated loading. describes simplified analysis, multihazard design piers, program results. Additionally, results from experiments are...

Past and current seismic design provisions for steel structures in Japan are presented compared with Canadian requirements. The performance of framed during the January 17, 1995, Hyogo-ken Nanbu earthquake is described. Numerous failures examples inadequate behaviour could be observed buildings various ages, sizes, heights, braced different structural systems. In moment resisting frames, damage included beams, columns, beam-to-column connections, column bases. Fracture bracing members or...

The metamodel is able to estimate hospital capacity and dynamic in real time incorporate influence damage structural non-structural components on ones. waiting main parameter it used evaluate disaster resilience index healthcare facilities. Its behaviour described using a double exponential function its parameters are calibrated based simulated data. covers large range configurations...

This paper reports the findings of research examining blast resistance bridge piers that are designed in accordance with current knowledge and specifications to ensure ductile seismic performance. Blast testing was conducted on 1/4 scale RC columns, nonductile columns retrofitted steel jacketing. The seismically jacketed did not exhibit a behavior under loading failed shear at their base rather than flexural yielding. A moment-direct interaction model proposed account for reduction direct...

A two-phase experimental program was generated on a full-scale two-story steel plate shear wall with reduced beam section connections and composite floors, to experimentally address the replaceability of infill panels following an earthquake seismic behavior intermediate beam. In Phase I, specimen pseudodynamically tested, subjected three ground motions progressively decreasing intensity. The buckled were replaced by new prior submitting subsequent pseudodynamic test cyclic failure in II. It...
