Abstract/Summary
Current fire design for wood framed buildings assumes a protective layer of charring and the material beyond that layer is entirely undamaged after the fire. It is documented that wood does experience a loss of ultimate capacity during a fire, however, the bulk of tests providing the reduction in capacity have been in tensile and compressive tests. The tests described in this paper were conducted to investigate the reduction in bending strengths both during and after being raised to pre-pyrolytic temperatures. These tests confirmed current design practices as laid out in the National Design Specification for Wood Construction 2024, while also suggesting that transient elevated-temperature effects and ductility loss may warrant further investigation.
