Shang, Y. (author), Nogal Macho, M. (author), Teixeira, Rui (author), Wolfert, A.R.M. (author)Transition zones such as level crossing and bridge approaches are critical links in railway networks due to higher degradation rates and maintenance needs. In this context, parametric optimization has been applied to improve the design in transition zones; however, it requires a more computationally efficient tool to support repetitive...journal article 2023

Arango, Erica (author), Nogal Macho, M. (author), Yang, M. (author), Sousa, Hélder S. (author), Stewart, Mark G. (author), Matos, José C. (author)The severe effects of extreme wildfire events in recent years have shown that the fire suppression approach is not enough to solve the problem. An alternative to dealing with this issue is to accept the impossibility of eliminating wildfire hazards and focus on preparing systems to be more resilient. However, existing decision-making tools...journal article 2023

Jiménez Rios, Alejandro (author), Plevris, Vagelis (author), Nogal Macho, M. (author)Bridge infrastructure has great economic, social, and cultural value. Nevertheless, many of the infrastructural assets are in poor conservation condition as has been recently evidenced by the collapse of several bridges worldwide. The objective of this systematic review is to collect and synthesize state-of-the-art knowledge and information...review 2023

Kammouh, O. (author), Nogal Macho, M. (author), Binnekamp, R. (author), Wolfert, A.R.M. (author)Construction project management requires dynamic mitigation control to ensure a project's timely completion. Current mitigation approaches are usually performed by an iterative Monte Carlo (MC) analysis which does not reflect (1) the project manager's goal-oriented behavior, (2) contractual project completion performance schemes, and (3)...journal article 2022

Bastidas-Arteaga, E. (author), Rianna, G. (author), Gervasio, H. (author), Nogal Macho, M. (author)The built environment is already facing severe consequences related to climate change. Considering the durability of structures, the increase of carbon-dioxide (CO<sub>2</sub>) concentration and changes on temperature and relative humidity may accelerate carbonation-induced corrosion, thus affecting the service life of reinforced concrete...journal article 2022

Teixeira, Rui (author), Martinez-Pastor, Beatriz (author), Nogal Macho, M. (author), O’Connor, Alan (author)Different emerging threats highlighted the relevance of recovery and adaptation modelling in the functioning of societal systems. However, as modelling of systems becomes more complex, its effort increases challenging the practicality of the engineering analyses required for efficient recovery and adaptation. In the present work, metamodels...journal article 2022

Teixeira, Rui (author), Martinez-Pastor, Beatriz (author), Nogal Macho, M. (author), Micu, Alexandra (author), O'Connor, Alan (author)Significant research has been conducted in identifying optimal recovery and adaptation decisions in disruptive scenarios using engineering models. In this context, an aspect that has been target of limited research is that of response times. Modelling is expected to grow progressively more complex as it becomes more accurate. Such complexity...conference paper 2022

Martinez-Pastor, Beatriz (author), Nogal Macho, M. (author), O'Connor, Alan (author), Teixeira, Rui (author)In traffic networks, some elements are more prone to suffer or to create disruptive situations, and the identification of these elements becomes a challenge due to the large number of possible threats. The following paper presents two new methodologies to identify and rank vulnerable and critical links of traffic networks. These methodologies...journal article 2022

Arango, E.A. (author), Santamaria, Monica (author), Nogal Macho, M. (author), Sousa, Helder S. (author), Matos, Jose C. (author)Assessing flood risks on road infrastructures is critical for the definition of mitigation strategies and adaptation processes. Some efforts have been made to conduct a regional flood risk assessment to support the decision-making process of exposed areas. However, these approaches focus on the physical damage of civil infrastructures without...conference paper 2022

Kammouh, O. (author), Kok, M.W.A. (author), Nogal Macho, M. (author), Binnekamp, R. (author), Wolfert, A.R.M. (author)Changes in a construction project schedule can impact the project's planned duration, resulting in penalties. A manual trial-and-error probabilistic approach is usually conducted to find an appropriate set of corrective measures to mitigate delays of the overall project. However, this approach does not capture the actual goal-oriented...journal article 2022

Shang, Y. (author), Nogal Macho, M. (author), Wolfert, A.R.M. (author)A co-simulation solution based on direct equilibrium of contact forces is proposed to simulate vehicle-track interaction (VTI) dynamics. It is developed in two platforms, which presents an iterative feedback loop that exchanges contact force files and structure response field in real-time. The load vector acting on the structure is described by...book chapter 2022

Nogal Macho, M. (author), Nogal, A. (author)Engineering models are becoming increasingly complex, involving a larger number of variables. As a result, engineers struggle to deeply understand the models and therefore validate and properly use them. Sensitivity analyses (SA) are usually conducted to help with this task. Nonetheless, the knowledge and computational efforts required to...journal article 2021
