Wind-Restraint System

Definition

A Wind-Restraint System is the collection of structural elements which provide restraint of the seismic-isolated structure for wind loads. The wind-restraint system may be either an integral part of isolator units or may be a separate device.

Purpose

The purpose of a wind-restraint system is to ensure that seismic-isolated structures remain stable and secure under wind loads, preventing excessive movement and potential damage.

Examples of Use

• High-Rise Buildings: Providing wind restraint for skyscrapers with seismic isolation.
• Bridges: Ensuring stability of bridges equipped with seismic isolators under wind conditions.
• Industrial Structures: Stabilizing large structures in areas prone to high winds and seismic activity.

Related Terms

• Seismic Isolation: A technique used to reduce the impact of seismic activity on structures.
• Load-Bearing Capacity: The maximum load a structure can safely carry.
• Structural Stability: The ability of a structure to maintain its position and integrity under various loads.

Notes

Wind-restraint systems must be carefully designed to complement seismic isolation systems, ensuring that structures can withstand both seismic and wind forces effectively.
