The role of steel in disaster-resistant buildings is crucial as it provides strength, durability, and flexibility. Steel is known for its high tensile strength, allowing it to withstand extreme forces such as earthquakes, hurricanes, and strong winds. It also has a high resistance to fire, making it ideal for protecting structures during fires. Additionally, steel's flexibility allows it to bend without breaking, absorbing and dissipating energy from seismic movements. Overall, steel plays a vital role in ensuring the structural integrity and safety of disaster-resistant buildings.
