Special Issue Information

Dear Colleagues,

Fire is a great threat to building structures; it can cause serious damages and even the collapse of entire buildings. The behaviour and safety of building structures in fire involve the development of building fires, fire detection and extinction, temperature-dependent material properties, the behaviour of structural elements, and global behaviour and collapse resistance of building frames. In addition, different structural systems behave differently in fire.

This Special Issue welcomes original research articles and review papers related to the behaviour and safety of building structures (e.g. steel structures, composite structures, concrete structures and timber structures) in fire. Topics of interest include (but are not limited to) the following:

Building fires;
Temperature-dependent material properties;
Behaviour of structural elements in fire;
Global behaviour and collapse resistance of building frames;
Post-fire behaviour and rehabilitation of building structures;
Emerging technologies related to the fire safety and structural fire engineering of buildings.

Abstract

To address the difficulty in conducting fire tests to verify the fire-resistance limit of large one-way slabs with heavy loads in a metro, a scale fire test method is proposed based on the bearing capacity calculation of the one-way slab under fire. The scale fire test method adapted the hypothesis that the deflection of the one-way slab under fire is close to a half-sine function and the plane section hypothesis. The validity of this hypothesis is verified through fire tests and finite element simulations. The scale fire test method achieves a similar temperature field and mechanical behavior between the scaled model and full-scale model of the one-way slab. The results of the fire tests showed that the temperature field and mechanical behavior of the scaled model were consistent with those of the full-scale model, with an error in fire resistance of 4.7%. The calculation results and fire test results are essentially consistent, with an error of 6.5%, and according to the calculation of the one-way slab fire-resistance limit, the key factor affecting the fire resistance of the one-way slab under fire is the temperature of the bottom rebars. Using the scale fire test method, the size effect of the one-way slab under fire still exists, and larger slabs have a greater deformation capacity. Full article

Influences of Species and Density on the Horizontal Flame Spread Behavior of Densified Wood

Abstract

Densified wood possesses outstanding mechanical properties and serves as a desired construction material for modern timber buildings. However, the limited research on its flame behavior hinders its broader applications. The authors of this paper experimentally and analytically investigated the influence of wood species and density on horizontal flame spread behavior. Densified oak and densified fir were tested. The flame spread rate decreased with wood density in both densified wood types. Their values were close at the same density. The mass loss rate (

\dot{m}

) of the densified wood decreased with the increase in wood density. The densified oak had higher

\dot{m}

due to its lower lignin content. Dimensionless correlations between the

\dot{m}

and density were obtained which agree with the experiments. The flame heights (L_f) of the densified wood also decreased with the increase in wood density. The densified oak had higher L_f due to its higher

\dot{m}

. As the densified wood density increased, the radiation (and conduction) was reduced (and enhanced), but the convection remained constant. The densified oak had lower convection, lower conduction, and higher radiation than the densified fir at the same density. Gas-phase heat transfer was dominant in the flame spread of the densified wood, but conduction was also significant as its contribution can be as high as 70% of gaseous heat transfer. Full article
