The International Building Code (IBC) is a comprehensive set of regulations and standards that govern building design and construction in the United States. One of the primary ways in which the IBC promotes safety is through its requirements for seismic and wind-resistant design.

Seismic design refers to the design of buildings to withstand earthquakes. The IBC includes specific requirements for seismic design based on the location and seismic hazard of the building site. The code requires that buildings be designed to resist lateral forces caused by earthquakes, including requirements for the strength and stiffness of structural elements, such as walls, floors, and roofs.
The IBC also includes requirements for seismic detailing, which involves the use of reinforcement and other measures to ensure that building components remain connected during an earthquake. This helps to prevent the collapse of buildings and reduce the risk of injury or death.
Wind-resistant design refers to the design of buildings to withstand high winds, such as those caused by hurricanes and tornadoes. The IBC includes specific requirements for wind-resistant design based on the location and wind hazard of the building site. The code requires that buildings be designed to resist the uplift and lateral forces caused by high winds, including requirements for the strength and stiffness of structural elements.
The IBC also includes requirements for wind-resistant detailing, which involves the use of reinforcement and other measures to ensure that building components remain connected during high winds. This helps to prevent the collapse of buildings and reduce the risk of injury or death.
In addition to these specific requirements, the IBC also provides guidance on how to assess the seismic and wind resistance of existing buildings. The code includes provisions for seismic retrofitting, which involves making changes to existing buildings to improve their ability to withstand earthquakes. The code also includes provisions for wind retrofitting, which involves making changes to existing buildings to improve their ability to withstand high winds.
Overall, the IBC plays a critical role in promoting safety through its requirements for seismic and wind-resistant design. By providing detailed requirements and guidelines for building design and construction, the code helps to ensure that buildings are safe and durable, even in the face of natural disasters. Through its requirements for seismic and wind-resistant detailing and retrofitting, the IBC helps to raise industry standards and promote best practices for building safety.
