Abstract:

There is a need to develop efficient multi-hazard performance based design (PBD) tools to analyze and optimize buildings at a preliminary stage of design. The first step was to develop a database and it is supported by five major contributions: 1) development of nomenclature of variables in PBD; 2) creation of mathematical model to fit data; 3) collection of data; 4) identification of gaps and methods for filling data in PBD; 5) screening of soil, foundation, structure, and envelope (SFSE) combinations.. A unified nomenclature was developed with the collaboration of a multi-disciplinary team t

Abstract:

With the increased push towards performance-based engineering (PBE) design, there is a need to understand and design more resilient building envelopes when subjected to natural hazards. Since architectural glass curtain walls (CW) have become a popular façade type, it is important to understand how these CW systems behave under extreme loading, including the relationship between damage states and loading conditions. This study subjects 3D computational models of glass CW systems to in- and out-of-plane loading simulations, which can represent the effects of earthquake or hurricane events. The

Abstract:

The importance of school buildings, among the built heritage of a community, is largely acknowledged. Due to past seismic events, damage or even collapse of schools have had a huge social impact. The safety of children and youth has a fundamental priority and, in addition, the unsafety of schools can aggravate social dispersion phenomena which follow an earthquake. In the aftermath of the Molise earthquake (2002), which caused the collapse of a primary school in San Giuliano di Puglia (Campobasso, Italy) and the consequent death of 27 children and a teacher, the Italian government issued a nat

Abstract:

Recent devastating earthquakes revealed that bridges are one of the most vulnerable components of the transportation systems. These seismic events have emphasized the need to mitigate the risk resulting from the failure of the bridges. Depending on the seismicity of the bridge local site, seismic vulnerability assessment of the bridges can be done based on the fragility curves. These curves are conditional probability functions which give the probability of a bridge attaining or exceeding a particular damage level for an earthquake of a given intensity level.

Unreinforced masonry (URM) structures have shown tobe susceptible to significant damage during strong earthquakes. Vulnerability assessment of URM buildings is needed so that appropriate mitigation strategies can be implemented. The existing Canadian practice consists of rapid seismic screening of buildings to assign priorities for further and more refined assessments, followed by refined analysis of individual critical buildings. The current seismic screening procedure, from 1992, is based on qualitative observations of seismic vulnerability, enabling the assignment of seismic priority ind

Abstract:

Tunnels, culverts, and subway stations are the main parts of an integrated infrastructure system. Most of them are constructed by the cut-and-cover method at shallow depths (mainly lower than 30 m) of soil deposits, where large-scale seismic ground deformation can occur with lower stiffness and strength of the soil. Therefore, the transverse racking deformation (one of the major seismic ground deformation) due to soil shear deformations should be included in the seismic design of underground structures using cost- and time-efficient methods that can achieve robustness of design and are easily

Thus, risk-targeted ground motion with 1% probability collapse in 50 years is adopted on ASCE 7-10.

Abstract:

This study focuses on the evaluation of seismic safety of masonry buildings in Turkey by using fragility curves. Fragility curves for masonry buildings are generated by two behavior modes for load bearing walls: in-plane and out-of-plane. By considering the previous research and site investigations, four major parameters have been used in order to classify masonry buildings with in-plane behavior mode. These are number of stories, strength of load-bearing wall material, regularity in plan and the arrangement of walls (required length, openings in walls, etc.). In addition to these four paramet

Abstract:

The emphasis on seismic design and assessment of reinforced concrete (RC) frame structure has shifted from force-based to performance-based design and assessment to accommodate strength and ductility for required performance of building. RC frame structure may suffer different levels of damage under seismic-induced ground motions, with potentials for formation of hinges in structural elements, depending on the level of stringency in design. Thus it is required to monitor the seismic behaviour and performance of buildings, which depend on the structural system, year of construction and the leve

Une étude comparative des méthodes paramétriques existantes avec l'hypothèse log-normale est d'abord réalisée. Elle permet ensuite de proposer des améliorations de la méthode du maximum de vraisemblance dans le but d'a

Abstract:

Drinking water systems will always face multiple challenges with respective to aging infrastructure, concerns related to water quality, uncertainty in supply and demand, disruptive events like environmental urgencies, natural disasters, and cyber and terrorist attacks. All of the above-mentioned incidents have the potential to disrupt a large part of a water system or the whole water distribution system either causing the damage to vital parts of infrastructure, affecting the human health, and interrupting service to consumers.Urban or metropolitan communities have experienced loss of infrastr

Abstract:

Il presente elaborato intende trattare il tema della vulnerabilità sismica del patrimonio edilizio esistente con riferimento agli edifici residenziali presenti in Emilia, caratterizzati da struttura a telaio in calcestruzzo armato con tamponamenti in muratura. L'obiettivo primario è la costruzione di curve di fragilità per via numerica, al fine di correlare una misura di intensità sismica alla probabilità di ottenere i vari livelli di danno previsti dalla scala macrosismica EMS-98. Parte del lavoro è incentrato sulla modellazione dei telai in c.a. irrigiditi da tamponamenti in muratura, al fin

Abstract:

This doctoral dissertation aims to report on the research work carried out and to provide a contribution to the field of seismic base isolation. Since its introduction, the base isolation strategy proved to be an effective solution for the protection of structures and their components from the earthquake-induced damage, enhancing their resilience and implying a significative decrease in time and cost of repair compared to a conventional fixed-base structure. Sliding isolation devices feature some important characteristics, over other devices, that make them particularly suitable for the appli

Abstract:

The damage occurred during recent earthquakes in many existing reinforced concrete (RC) buildings designed before the introduction of modern anti-seismic codes has shown that these structures are very vulnerable to the seismic action due to their reduced ductility capacity. This underlines the need to develop retrofit techniques for reducing the vulnerability of existing structures and of reliable tools for assessing the effectiveness of the retrofit and the resulting structural safety. Earthquake risk mitigation and seismic risk evaluation are among the engineering's most complex challe

Abstract:

Abstract : Fragility curves are a very useful tool for seismic risk assessment of bridges. A fragility curve describes the probability of a structure being damaged beyond a specific damage state for different levels of ground shaking. Since more than half of all bridges in the province of Quebec (Canada) are in service for more than 30 years and that these bridges were designed at that time without seismic provisions, generating fragility curves for these structures is more than necessary. These curves can be used to estimate damage and economic loss due to an earthquake and prioritize repairs

Obbiettivo della tesi è sviluppare un metodo che valuti la probabilità di rottura arginale nella stesura delle mappe di pericolosità e di rischio alluvione. Ad oggi le mappe di pericolosità, redatte dagli enti regionali, considerano solo la probabilità di superamento dell’argine da parte del livello idrico (overtopping) e non il cedimento dello stesso a causa dell’instabilizzazione dovuta all’innalzamento del livello del fiume. Per la presente tesi si è scelto come caso di studio la rottura dell’argine destro del fiume Secchia del 19 gennaio 2014, presso la frazione di San Matteo, comune di Mo

Abstract:

L’obiettivo della tesi è di valutare, nei risultati di un’analisi sismica, l'incidenza dell’incertezza data dalla scelta del legame costitutivo in tre differenti modalità di collasso. Si studia quanto sia importante la scelta di un legame costitutivo, per la descrizione delle cerniere plastiche, ai fini di una maggiore precisione nella risposta della struttura. Per cui, una volta definita la struttura e scelto un set di accelerogrammi, si effettua un’analisi incrementale dinamica andando a cambiare, per ogni analisi, il legame costitutivo. Questo procedimento è stato ripetuto per le tre modali

Abstract:

Nowadays, earthquakes are one of the most catastrophic natural events that have a significant human, socio-economic and environmental impact. Besides, based on both observations of damage following recent major/moderate seismic events and numerical/experimental studies, it clearly emerges that critical non-structural components (NSCs) that are ubiquitous to most industrial facilities are particularly and even disproportionately vulnerable to those events. Nonetheless and despite their great importance, seismic provisions for industrial facilities and their process equipment are still based on

The premiums of these policies can be easily estimated through historical loss data and law of truly large numbers. However, the natural disaster risk cannot be estimated in advance. In addition, insurance companies cannot calculate the premiums of catastrophe insurance correctly because they lack of quantitative date for that. Therefore, insurance companies need a new method to manage the landslide risk. This study uses the discrete model of the expected loss to
