This study aims to assess the impacts of seismic events on subway station structures and their evacuation routes, focusing on a human-centric approach to disaster preparedness. Using PLAXIS 2D for dynamic numerical simulations and the Dijkstra Algorithm for evacuation modeling, this research investigates how structural damage from earthquakes affects the evacuability of subway stations. The findings highlight that as earthquake magnitude increases, evacuation routes become significantly more constrained, leading to a sharp rise in evacuation difficulty and potential bottlenecks, thereby exacerbating the risk of casualties. Additionally, the analysis found that structural sections located on softer ground are more susceptible to severe damage, further impeding evacuation efforts. By addressing the practical implications of seismic impacts on evacuation routes, this work provides comprehensive insights into the risks faced by subway station occupants during seismic events. The study offers insights for enhancing emergency response strategies and underscores the necessity for a multidisciplinary approach to disaster preparedness, integrating structural engineering and evacuation route design to ensure the safety and resilience of urban subway systems during emergencies.</div></div>","PeriodicalId":34137,"journal":{"name":"Developments in the Built Environment","volume":"21 ","pages":"Article 100637"},"PeriodicalIF":6.2,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143591525","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper examines a fire drill in a multi-functional university building in Hong Kong with over 800 participants. While capturing every participant's evacuation process was challenging, key location recordings allowed for a detailed analysis of corridors, staircases, and exits. The analysis revealed that nearly 50% of participants delayed responding to fire alarms, with some remaining in their rooms for over four minutes. Furthermore, exits experienced imbalanced utilization rates, and one was over 200% of design capacity, revealing occupants' preference for familiar routes. Additionally, it highlights the importance of fire drills and discusses future roadmap combining advanced techniques.

The findings show that visual attention shift interventions reduce the likelihood of re-engaging in pre-evacuation activities while improving evacuation performance when compared to auditory cues. Continuous visual cues were more effective than auditory cues in keeping attention during evacuation.

The porous nature of hydrochar proves to be advantageous, positively impacting the thermal characteristics of the plasters.

This paper investigates an IT artefact called the Construction Logistics Control Tower (CLCT). A CLCT is a control tower artefact specifically focusing on optimizing construction logistics activities across the supply chain. We distinguish four potential construction logistics application fields and, therefore, describe four potential variants of the CLCT. We design and narrow down these alternatives by applying a form of co-creation in which stakeholders design and set requirements for the artefact of interest. Our goal is to develop a reference architecture for the strategic and operational form in Enterprise Architecture. We focus on a transportation-based CLCT, which has a strategic component, <em>i.e</em>., it predicts and manages long-term logistics activities regarding construction, and an operational one, <em>i.e</em>., it operationalizes and executes daily transportation processes to support construction activities. Our work provides a core enterprise architecture diagram describing this CLCT variant’s main functionalities. Next, we find that three key technologies need to be combined to realize such a system: Building Information Modelling, Geographic Information System and Transportation Management System. We discuss potential hurdles in the integration process and reflect on potential solutions. In the end, we envision that the construction of such a CLCT takes both a bottom-up and top-down approach but at least should be supported by a large consortium of stakeholders, constructing and supporting the system from their interests.</div></div>","PeriodicalId":34137,"journal":{"name":"Developments in the Built Environment","volume":"21 ","pages":"Article 100625"},"PeriodicalIF":6.2,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143464910","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
