What type of wall must have sufficient structural stability under fire conditions to allow for the collapse of construction on either side without collapsing itself?

A firewall is designed to provide structural stability and protect adjacent spaces from the spread of fire. It must be constructed to withstand fire conditions long enough to allow for the potential collapse of surrounding structures without compromising its own integrity. This means that during a fire, even if the construction on either side of the firewall fails, the firewall itself must remain standing to contain the fire and prevent it from spreading.

Firewalls are often built with specific materials and construction techniques that enhance their fire-resistance rating, making them crucial components in building safety and fire prevention strategies. In contrast, partition walls are not meant to bear loads or provide such protection. Load-bearing walls support structural weight and may not be designed for fire-resistance. Shear walls, while they provide lateral support against wind and seismic activity, do not necessarily have the same requirements for fire resistance and structural stability in the face of fire conditions as firewalls do.
