Appendix A The Effects of Fire on Structural Systems

Appendix AThe Effects of Fire on Structural Systems A-3 Apart from losing practically all of its load-bearing capacity, unprotected steelwork can undergo considerable expansion when sufficiently heated. The coefficient of expansion is 10-5 per degree Celsius. Youngs modulus does not decrease with temperature as rapidly as does yield strength.Alternatives to Wooden Frames in ConstructionMay 21, 2019 · Aside from the disadvantage to the use of wooden frames in constructing houses and buildings, one more threat that the alternative materials bypasses is their higher resistance to fire damage. Wood is a highly flammable material and therefore makes it impossible for a structure that uses it as a frame to survive a fire accident.After burn | Driver Group PlcMaterials testing and detailed damage assessment; fire damage assessment of hot rolled structural steelwork Steel has a high thermal conductivity and unprotected steelwork will rapidly increase in temperature during a fire.
