Digital Twins (DTs) are forecasted to be used in two-thirds of large industrial companies the next decade. In Architecture, Engineering and Construction (AEC) sector, their actual application is still largely at prototype stage. Industry academia currently reconciling many competing definitions unclear processes for developing DTs. There a compelling need establish DTs as practice AEC by common procedures standards tailored sector's use cases. This paper proposes step-by-step workflow...
The number of offshore wind turbine farms in seismic regions has been increasing globally. performance steel monopile-supported turbines, which are the most popular among viable structural systems, not investigated thoroughly and more studies needed to understand potential vulnerability these structures during extreme events develop reliable design assessment procedures. This study investigates a typical subjected strong ground motions. Finite element models an developed unscaled natural...
The Central Italy earthquake sequence initiated on 24 August 2016 with a moment magnitude M6.1 event, followed by two earthquakes (M5.9 and M6.5) 26 30 October, caused significant damage loss of life in the town Amatrice other nearby villages hamlets. significance this led to major international reconnaissance effort thoroughly examine effects disaster. Specifically, paper presents evidences strong local site (i.e., amplification seismic waves because stratigraphic topographic that leads...
Very large tsunamis are associated with low probabilities of occurrence. In many parts the world, these events have usually occurred in a distant time past. As result, there is risk perception and lack collective memories, making tsunami communication both challenging complex. Furthermore, immense challenges lie ahead as population exposure continue to increase coastal areas. Through last decades, caught populations off-guard, providing evidence preparedness. Recent tsunamis, such Indian...
The influence of flow velocity on structural damage induced by tsunami inundation is investigated to improve empirical fragility models considering as explanatory hazard variable in addition depth. analysis based extensive data for the 2011 Tohoku earthquake collected Ministry Land, Infrastructure, and Transportation Japanese Government. Multivariate curves are developed through multinomial logistic regression un-binned data. This approach facilitates flexible development various nested...
Summary The increasing number of wind turbines in active tectonic regions has attracted scientific interest to evaluate the seismic vulnerability offshore (OWTs). This study aims at assessing deformation and collapse susceptibility 2MW 5MW OWTs subjected shallow‐crustal pulse‐like ground motions, which not been particularly addressed date. A cloud‐based fragility assessment is performed quantify response for a given intensity measure assess failure probabilities non‐pulse‐like motions....
Herein we investigate Life Cycle Cost (LCC) and Return on Investment (ROI) as potential decision variables for evaluating the economic performance financial feasibility of a set flood mitigation strategies over time. The main novelty this work is application LCC ROI analyses at urban level to an asset portfolio flood-prone buildings. Reduced damage treated probabilistically avoided costs (LCC analysis) returns (ROI analysis), respectively. proposed methodology applied case Dar es Salaam,...
This study develops a probabilistic multi-hazard loss estimation methodology for coastal communities which are exposed to cascading shaking-tsunami hazards caused by offshore mega-thrust subduction earthquakes. The method captures the common source effects simulating shaking and tsunami risks. It facilitates quantitative evaluation of accounting uncertainties associated with based on novel stochastic earthquake modeling state-of-the-art fragility modeling. A case is set up illustrate an...
Abstract This study establishes a multi‐hazard probabilistic assessment framework for assessing the integrity of monopile offshore wind turbines (OWT) under stochastic coupled effect wind, wave and earthquake loading. The procedure deals with entire operational range inflow speed (i.e., 3–25 m/s), which probability failure excitations is found to be non‐negligible. Numerical analysis performed by implementing nonlinear finite‐element models OWT developed in OpenSees. dynamic response system...
This study develops a novel simulation-based procedure for the estimation of likelihood that seismic intensity (in terms spectral acceleration) and tsunami inundation wave height), at particular location, will exceed given hazard levels. The accounts common physical rupture process shaking tsunami. Numerous realizations stochastic slip distributions earthquakes having different magnitudes are generated using scaling relationships source parameters subduction zones then synthesis method...
Abstract Flood risk maps for the built environment can be obtained by integrating geo-spatial information on hazard, vulnerability and exposure. They provide precious support strategic urban planning decision-making. These maps, generated in a probabilistic framework, consider various sources of uncertainty flood assessment such as occurrence extreme flooding events, future land use cover, characteristics buildings, exposure to flooding. This paper investigates how these used complicated...
The Central Italy earthquake sequence nominally began on 24 August 2016 with a M6.1 event normal fault that produced devastating effects in the town of Amatrice and several nearby villages hamlets. A major international response was undertaken to record this disaster, including surface faulting, ground motions, landslides, damage patterns structures. This work targeted development high-value case histories useful future research. Subsequent events October exacerbated previously affected...
Delineation of flood risk hotspots can be considered as one the first steps in an integrated methodology for urban management and mitigation. This paper presents a step-by-step GIS-based framework identifying flooding residential buildings. is done by overlaying map potentially flood-prone areas [estimated through topographic wetness index (TWI)], [extracted from city-wide assessment morphology types (UMT)], geo-spatial census dataset. The novelty this consists fact that (the TWI thresholds)...
Summary During a mainshock‐aftershock (MSAS) sequence, there is no time to retrofit structures that are damaged by mainshock; therefore, aftershocks could cause additional damage. This study proposes new approach develop state‐dependent fragility curves using real MSAS records. Specifically, structural responses before and after each event of sequences used obtain statistical relationships among the engineering demand parameter prior seismic ( pre‐EDP ), intensity measure IM post‐EDP ). The...
Abstract Developing an effective tsunami evacuation plan is essential for disaster risk reduction in coastal regions. To develop plans, real transportation network, interaction among evacuees, and uncertainties associated with future events need to be considered a holistic manner. This study aims such integrated approach using agent-based simulation advanced stochastic hazard assessment. As case study, urban area Padang, Indonesia, threatened by tsunamis from the Mentawai–Sunda subduction...
