A kriging metamodel with adaptive sampling for seismic evaluation of podium buildings
(2023)In this paper, nonlinear time-history dynamic analyses of selected earthquake ground motions are conducted on designated wood-frame podium buildings and the resulting inter-story drifts are analyzed. We aim to construct a ... -
A machine learning-based approach to evaluate the fire resistance of timber columns
(2023)Timber construction offers substantial advantages in terms of sustainability, ease of modular construction, and aesthetics. In recent years, structural members made from timber have been increasingly used in residential ... -
A Markovian framework for multi-hazard life-cycle consequence analysis of deteriorating structural systems
(2023)Multiple-hazard (or simply multi-hazard) interactions are either disregarded or addressed inadequately in most existing computational risk modelling frameworks for natural hazards, leading to inaccurate life-cycle consequence ... -
A Method for Probabilistic Analysis in Structural Dynamics Based on Separation of Aleatory and Epistemic Uncertainties
(2023)There is still much philosophical debate about whether a frequentist or subjective view of probability should be adopted. Some uncertainties (typically aleatory uncertainties) are naturally modelled using a frequentist ... -
A methodology for assessing the load capacity of cantilevered stone stairs
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2012)Cantilevered stone stairs were widely constructed from the 17th to the 20th century. Thousands of these stairs were built in Ireland and across Europe during this period and they have proven to be very robust. However, the ... -
A Modern Bayesian Approach to Model Updating of Bridges Considering Measurement Uncertainty
(2023)Existing bridges were designed using contemporaneous standards, but increased loading due to increased freight demand must be considered in their ongoing safety management. Finite-Element (FE) modelling provides the ... -
A new approach to driving cycle development and its applications
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2013)Driving cycles describe the general driving pattern of a vehicle in a road network, and are usually represented by speed-time profiles of equal spacing. They are used to approximate and represent driving conditions as an ... -
A new technique for vortex methods in computational fluid dynamics
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2002)The random vortex method is a Lagrangian technique which involves solving the stream function-vorticity formulation of the Navier-Stokes equations. Discrete vortex particles, which are created at the surface to satisfy ... -
A novel design equation for reinforced concrete columns confined by FRP and steel based on advanced finite element analysis
(2023)Strengthening of reinforced concrete (RC) columns using externally-bonded fiber-reinforced polymers (FRP) is a widely accepted and used retrofit technique. The FRP encasing increases the vertical load capacity and ductility ... -
A novel end-user-oriented approach to dynamic post-disaster resilience quantification for individual facilities
(2023)Community recovery from a disaster is a complex process, in which the importance of different types of infrastructure functionality can change over time. For instance, sheltering facilities can be critical in the immediate ... -
A parallel Bayesian interval optimization approach for static analysis of structures with interval uncertainties
(2023)This paper aims at approximating the bounds of the static response of structures with interval uncertainties. Such task is often challenging due to the large number of computationally intensive response evaluations required. ... -
A performance-based probabilistic framework to model risk to power systems from hurricanes
(2023)Utility companies are often prepared for small-scale blackouts under normal operating conditions. However, they face crucial challenges with extreme weather events, such as hurricanes. Utilities must make risk-informed ... -
A practical framework for strategic noise mapping
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2008)Environmental noise is a major form of pollution and it is estimated that at least one quarter of the population of the EU suffer a reduced quality of life due to exposure to noise. To address the problem the European Union ... -
A preliminary methodology for multi-hazard risk assessment of large bridge portfolios using quantitative indicators
(2023)In the last years, several catastrophic collapses of existing bridges have raised growing awareness to the need for structural assessment, health monitoring, and retrofitting by public institutions and infrastructure ... -
A Probabilistic Approach to Estimating Post-disaster Unmet Housing Needs Under Limited Information
(2023)This paper presents a methodology to estimate post-disaster unmet housing needs that is accurate and relies only on data obtained shortly after a disaster. Statistical models for aid distributed by the Federal Emergency ... -
A Probabilistic Framework for Post-Disaster Recovery Modeling of Buildings in Developing Countries
(2023)Post-disaster recovery is a significant challenge, especially in developing countries. As a result of various technical, environmental, socioeconomic, political, and cultural factors influencing post-disaster recovery, ... -
A probabilistic framework for the assessment of bridges for once-off superloads
(2023)The transportation of once-off superloads is often treated using the same reliability levels as for new bridges which experience frequent normal and abnormal traffic loads for a remaining life of 100 years. An example of ... -
A Proposed Fuzzy-based Optimisation Model for Evaluating Construction Projects' Risk Response Strategies
(2023)The aim of this paper is to develop a fuzzy-based optimisation model for selecting the most appropriate construction risk response strategies by surveying construction experts in Iraq. A two-step research methodology was ... -
A quasi three dimensional numerical model for terrain propagation
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2002)Numerical modeling techniques provide a powerful tool for the optimization of modern land mobile radio communications systems. Mathematically, propagation over terrain constitutes a three-dimensional vector field problem ... -
