Smoke Hazards of Tall Timber Buildings with New Products

Timber buildings can now stand very tall using new products. As timber materials are expected to be easily ignitable, the fire hazard of timber is a concern. Charring of the timber surface would maintain structural stability, but would also be accompanied by smoke. Although treating timber products with fire retardants would delay the ignition time under low radiative heat flux, toxic combustion products and unburnt fuel would be emitted immediately upon burning. More smoke and higher toxic gas concentrations such as carbon monoxide would be given off upon burning some fire retardants under high flashover heat fluxes. Due to the fast upward movement of smoke under stack effect, spreading of toxic smoke in tall timber buildings would lead to a hazardous environment. Engineered timber consists of derivative timber products. New engineered timber products are manufactured with advanced technology and design, including cross-laminated-timber (CLT), laminated veneer lumber (LVL) and glue-laminated timber (Glulam). The fire behaviour of timber products has been studied for several decades. However, the smoke hazards of using new timber products in building construction should be monitored. The objective of this study is to inspire stakeholders in fire safety of timber buildings, inter alia smoke hazards, to use new timber products to build tall buildings.

“…In order to meet the objective of adequate fire protection, public buildings are equipped with passive and active fire protection systems [1][2][3]. One of the applications that are currently being implemented is the use of smoke vents, which are designed to remove smoke and heat during a fire [4,5]. They are an extremely important element of any smoke exhaust system.…”

The aim this paper is to present the simulation of the building in the computer program PyroSim by Thunderhead Engineering based on the FDS calculation engine. The article presents simulations of the use of smoke vents and their impact on fire safety in a public building based on the Fire Dynamics Simulator (FDS) calculation engine. Two scenarios were analysed in the simulation. The first simulation shows 180 seconds of fire without the smoke vent, while the second simulation shows 150 seconds of fire with the smoke vent open. A fire power density of 500 kW/m2 was adopted and is used in each case as well as the fire development coefficient, which was calculated on the basis of literature data. On their basis, simulations were carried out, the results of which were used to draw conclusions.

“…Some use timber to design new building structures to improve energy efficiency and reduce greenhouse gas emissions, such as a combination of glued laminated timber with steel stud and a combination of laminated veneer lumber with steel stud [17], timber–glass composite wall panels [18], and cross‐laminated timber structures [19]. In the research of the fire‐fighting system, the timber itself is flammable, so the research is mostly about the fire‐fighting measures and ventilation and smoke extraction of timber structure buildings [20, 21].…”
