Previous research has shown that the propensity for a window to fail in a wildland-urban interface (WUI) fire incident depends on the window frame material and construction. However, the degree to which window frame materials affect their performance in a WUI fire incident is unclear. The objective of the present work is to identify failure mechanisms and rank the relative performance of common window frame materials, which will ultimately provide guidance on window selection in regions susceptible to WUI fire events. Experiments were conducted to investigate the performance of four types of window frame assemblies (vinyl, wood, fiberglass, aluminum) under fire exposures similar to those from a structure fire to an adjacent structure. Window failure events were identified, and the number of occurrences of each event, the time to the occurrence of each event, and heat load (heat flux integrated over time) at each event occurrence were compared between window frame assembly types. Failure mechanisms differed between frame types, and both the design and construction of components within the frame assemblies notably impacted failure. Wood and vinyl frame assemblies were the most vulnerable to failure, having the greatest number of sash failures. Furthermore, all wood frame assemblies ignited. Aluminum frame assemblies performed best and would likely provide the highest level of performance in regions susceptible to WUI fires.</p></div>","PeriodicalId":558,"journal":{"name":"Fire Technology","volume":"62 4","pages":""},"PeriodicalIF":2.4,"publicationDate":"2026-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10694-026-01905-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147829782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Of all SCMs, Rice Husk Ash (RHA) and Silica Fume (SF) are silica-rich materials but provide different reactivity and pore refinement level, which necessitates their side-by-side comparison. This review systematically summarizes the effects of RHA and SF on concrete at high temperatures, focusing on strength development, thermal degradation, spalling resistance, and microstructure evolution. These parameters are important because they control the residual load bearing capacity, repairability, and long-term safety of fire-damaged structures. It is found that the fire resistance improvement effects of RHA mainly include pore structure refinement and internal curing effect which alleviates thermal cracking, while those of SF mainly involve increased matrix densification and pozzolanic formation of additional calcium silicate hydrate (CSH) gel, thus enhancing the compactness of cementitious matrix at elevated temperatures due to higher content and reactivity of amorphous silica in SF than those in RHA. But critically, many gaps exist concerning the role of heating–cooling regimes, SCM hybrid interactions and the absence of standardized fire-testing protocols for RHA- and SF-modified concretes. Through the comparative perspective of their performance trends and fundamental mechanisms, this review elucidates the complementary action of RHA and SF in which the former enhances thermal stability via pore modification and internal curing; whereas matrix densification derived from high pozzolanic reactivity, possessed by nature within SF, constitutes a better framework to design for fire-resistant concrete systems.</p>\u0000 </div>","PeriodicalId":558,"journal":{"name":"Fire Technology","volume":"62 4","pages":""},"PeriodicalIF":2.4,"publicationDate":"2026-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147797181","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study proposes a unified function to represent the vertical temperature distribution of fire-induced flow from the ceiling to the floor in the tranquil flow region in tunnels with rectangular cross-sections, under naturally ventilated conditions and with no longitudinal gradient. The function parameters are normalized with respect to the tunnel aspect ratio and expressed as functions of distance from the fire source, incorporating both geometric and thermal effects. The proposed function accurately captures the spatial variation of vertical temperature distributions and is applicable to tunnels with various aspect ratios and heat release rates. It also enables reliable estimation of smoke layer thickness, producing values consistent with experimental data. Comparative analyses using small- and full-scale tunnel experimental data, as well as full-scale tunnel numerical simulation data, confirm that the proposed function reasonably captures the vertical temperature distribution from the ceiling to the mid-height of the tunnel, while also naturally representing the distribution from mid-height to the floor, provided that it is applied under conditions where the Froude number is less than 0.9.</p>\u0000 </div>","PeriodicalId":558,"journal":{"name":"Fire Technology","volume":"62 4","pages":""},"PeriodicalIF":2.4,"publicationDate":"2026-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10694-026-01909-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147752446","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several closed-form approximate solutions of the smoke filling can be found in the literature for flat roofs. However, the smoke filling under sloping roofs is quite different, and none of existing closed-form solutions is applicable to the sloping-roof scenarios. In this work, the smoke filling in enclosure growing fires with floor leaks and sloping roofs is derived. The smoke filling process is divided into two stages. The first is the smoke filling in the upper part of the room, i.e., the triangular prism enclosed by the roof panels and the gables. The second is the smoke filling in the lower part of the room when the smoke layer expands beyond the triangular prism. For the first stage, a novel closed-form solution is derived through asymptotic analyses based on introduction of a virtual scenario. In the virtual scenario, the smoke filling is exactly the same as that in the real scenario only when the smoke interface is higher than the gable base or the corresponding level. This closed-form solution agrees well with the numerical solution. For the second stage, the concept of \"equivalent flat roof\" is introduced to make the existing solutions applicable and a method is proposed to estimate the equivalent flat-roof height. Since the proposed models are based on the Zukoski plume correlation, a coefficient is introduced into the entrainment plume term to reflect the correlation's uncertainty. An illustrative example is presented to demonstrate how to derive the descent smoke layer time as a function of the smoke layer interface height. It is shown that the proposed solutions work well for both the stages.</p>\u0000 </div>","PeriodicalId":558,"journal":{"name":"Fire Technology","volume":"62 3","pages":""},"PeriodicalIF":2.4,"publicationDate":"2026-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147738075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
