Star Seismic Buckling Restrained Braces

Star Seismic is an industry leader in the engineering and design of buckling restrained braces (BRBs). Their BRBs deliver improved seismic response through a yielding core with an engineered separation from the surrounding concrete and steel casing.

Star Seismic’s Buckling Restrained Braces (BRBs) can be used to meet seismic design requirements on even the most demanding projects. From commercial structures and high-rise buildings, to state-of-the-art medical centers and stadiums, they’re BRB systems have been featured on a wide range of award-winning construction projects all over the globe.

Buckling restrained braces are ideal options for construction retrofits and building projects that are hampered by heavy time constraints. They also can be used on structures that present a unique combination of seismic and aesthetic demands. Other applications where Star Seismic’s BRBs can be utilized include industrial structure, government buildings, utility stations, parking garages and military bases.

Passive Energy Dissipation

The main purpose of incorporating devices that are capable of passively dissipating energy during an earthquake is to reduce loading on main structural members. These devices are specifically designed to absorb energy produced during a seismic disturbance so that the most important sections of a structure remain undamaged.

This typically results in reduced lateral deformation (total and relative displacement), which helps prevent damage to many non-structural elements such as dividing walls, finished walls and facades.

This concept of dissipation, also known as supplementary seismic damping, has been used with a great deal of success in the design of many state-of-the-art buildings located in highly seismic regions all over the world.

The most common types of dampers include:

  • ADAS
  • Viscous (Taylor)
  • Buckling Restrained Braces (BRB)

Seismic Isolation

Seismic base isolation is one of the most commonly used means of protecting a structure from seismic vibrations. It involves placing devices known as isolators at the base of a building or non-building structure, which change the period of vibration and preserve the building’s structural integrity.
