Which construction type features structural members that are noncombustible and will not ignite?

Fire-resistive construction is designed specifically to withstand high temperatures and resist ignition, which makes it notable for its noncombustible structural members. This type of construction typically includes materials such as concrete, steel, and certain types of masonry, which do not burn and provide greater fire safety.

Buildings constructed with fire-resistive materials are engineered to maintain their structural integrity for longer periods during a fire, allowing for safer evacuation and increased time for firefighting efforts. Fire-resistive construction plays a crucial role in high-rise buildings, hospitals, and other facilities where it's vital to prevent the spread of fire and smoke, thereby protecting both occupants and responders.

In contrast, wood-frame construction, lightweight construction, and platform construction are more susceptible to ignition and fire spread due to the inherent combustible nature of the materials used. These types of construction can present increased risks in a fire scenario, as they are designed primarily for cost-effectiveness and ease of construction rather than for maximizing fire resistance.
