Abstract This paper describes selected observations, measurements, and analysis from a series of large-scale experiments on cross-laminated timber (CLT) slabs that were exposed to fire below, using four different heating scenarios, with sustained mechanical loading 6.3 kN m per metre width slab. The deflection response in-depth temperatures are used compare the experimental against relatively simple structural model assess load bearing capacity CLT elements in fire, including during decay...
Abstract This paper describes fire tests on loaded glued laminated timber columns in which the structural response was measured during heating and cooling phases. Identical with 280 × mm 2 cross‐section 3.7 m length were tested under various durations a standard furnace to investigate integrity full burnout. Two of subjected ISO 834 until failure their resistance 55 58 min, respectively. 15 min followed by controlled cooling; these failed phase, respectively after 98 153 min. Flame...
Summary An experimental study of the influence an exposed combustible ceiling on compartment fire dynamics has been performed. The in compartments with cross‐laminated timber ceilings vs non‐combustible reinforced concrete otherwise identical three different ventilation factors were investigated. results are compared against predictions from two theoretical models for dynamics: (a) parametric model given EN 1991‐1‐2, and (b) a developed at Technische Universität Braunschweig, which currently...
Abstract Post‐flashover fires inherently lead to external fire plumes, constituting a hazard for rapid spread over façades. As multi‐storey mass timber buildings with internal visible surfaces become more common, there are concerns that such would produce larger plumes and hazards (assuming all other parameters equal). The literature reveals only indications of this, how the actual exposure relates different test methods assessment is unknown. Here we utilise series full‐scale compartment...
Summary In this paper, a comparative simulation study on 3 large‐scale facade testing methods, namely, the SP Fire 105, BS 8414‐1, and ISO 13785‐2 is presented. Generally good correspondence between simulations experimental data has been found, provided that thermal properties of material heat release rates are known; however, deviates in close proximity fire source. Furthermore, statistical ensemble for evaluating effects stemming from uncertainty input used. Here, it was found using...
High-performance concrete (HPC) is one of the most recent types among materials used routinely in building and civil structures. Their development structures applications growing need for justification their fire resistance has led several laboratories to carry out research on properties at high temperature. This letter presents some main aspects related physicochemical changes, thermal mechanical It introduces a State The Art prepared by RILEM Technical Committee 227-HPB (Physical behaviour...
Summary Standard fire resistance tests have been used in the design of structural building elements for more than a century. Originally developed to provide comparative measures level safety noncombustible products and elements, recent resurgence engineered timber construction raises important questions regarding suitability standard combustible elements. Three floor (5.9 m × 3.9 plan), one on concrete slab two cross‐laminated (CLT) slabs, were undertaken explore some relevant issues. The...
Summary The results presented in this paper are part of a multi‐partner collaborative project named ‘The Épernon Fire Tests Programme’, the purpose which is to analyse different behaviours combustible and non‐combustible loaded structures when they tested under standard ‘natural’ fires. has several objectives, such as quantification energy participation materials fire tests, influence surfaces ventilation factors on dynamics compartment fires, thermo‐mechanical behaviour concrete timber...
Summary A comparison between full‐scale façade fire tests where SP Fire 105 and BS 8414‐1 were used regarding repeatability the use of modeling to discern changes in setups is presented. Two test series according repeated outside using same systems on 2 different days, whereas for a set common Sweden tested indoors. In particular, results show that wind around setup may have significant impact heat exposure surface will depend thickness specimen an increased temperature front façade,...
Summary The impact of different passive protective measures against external vertical fire spread was investigated using the numerical tool Fire Dynamics Simulator (FDS). study divided into a validation and comparative analysis. performed to evaluate FDS as calculation for modelling conducted experimental results from large‐scale test done on SP FIRE 105 rig at SP, Sweden. It concluded that 6.2.0 could reproduce with reasonable level detail. In analysis, smaller apartment studied in...
Summary The addition of polypropylene (PP) fibres has been shown to reduce the fire spalling propensity concrete. When including this type in concrete, concrete mix becomes less robust, and small deviations constitutes change workability properties So, from a manufacturing perspective as dosages possible PP are desirable. Very few large‐scale resistance tests loaded compression exist showing function at low on mixes sensitive if no added. In paper, results 26 presented analysed. test four...
Summary Concrete spalling is an important phenomenon to consider when evaluating the fire behavior of concrete, as this can sometimes have impact on structural capacity studied element. Spalling be assessed experimentally using screening tests although it influenced by size, geometry, and boundary conditions tested element, among other factors. No standardized systematic methods are yet available assess concrete sensitivity testing. Plus, comparative results between screenings (small medium...
In this paper a comparison between test and modelling results are performed for two large-scale façade fire testing methods, namely SP Fire 105 BS 8414-1. order to be able compare tests the uncertainties have quantified both in modelling. Here we present methodology based on deterministic sampling quantify input. We find, general good agreement models results. Moreover, temperatures estimated by plate thermometers is indicated less sensitive small variations model input thus suitable these...

In second time critical conditions theatre calculated. participants given clear instructions on building layout and heat release rate for cases. Still, results demonstrate significant variation (range 110 seconds)...
This special issue of Fire and Materials presents global research into timber structures fire safety. follows the renewed momentum in sustainable design 21st century. Contemporary practitioners researchers are tasked with a need for information safety these from sustainability point view, important combination other (Figure 1). The was conceived late 2020. A call papers issued 2021 advertised on many different social media-based platforms. Practitioners were invited to submit contributions...
This paper presents the data and results of seven fire tests performed on glue laminated timber columns in a compartment built especially for which wood cribs created so-called natural fire.These are part research programme titled "burnout resistance" to establish new methodology better describe performance structural elements during whole duration fire.Comparisons with similar made resistance furnace allow comparing charring rates observed standard conditions fires.
