Which type of construction does fire cut enhance safety for during a fire?

Fire cut is a technique used primarily in wooden construction to enhance safety during a fire. It involves cutting the ends of wooden joists at an angle to allow them to pivot and fall away from the bearing walls when exposed to heat. This shear effect prevents the wooden joists from becoming trapped and potentially causing the collapse of structures as the wood weakens due to heat exposure.

In contrast, steel beams, concrete structures, and brick walls behave differently when subjected to fire. Steel can lose strength at elevated temperatures but does not require special cutting for safety. Similarly, concrete and masonry materials like brick are less affected by fire and do not require this kind of strategic construction technique for enhanced fire safety. The specific design of wooden joists with fire cuts is crucial for maintaining the integrity of the structure during a fire, making it particularly relevant to wooden construction.
