Description
Although buckling restrained braces (BRB) have now been a codified system in the US for over five years and have been used in design for much longer, the system is still relatively new in New Zealand. BRB’s are now entering their second US code cycle with the AISC Seismic Provisions for Structural Steel Buildings, AISC 341-10, which has introduced significant changes. In addition, several key issues of current research will be discussed that are contributing to the next set of code requirements for 2016. These new changes will be highlighted along with methods to effectively design Buckling Restrained Braced Frames (BRBF) using New Zealand codes. The latest innovative uses for BRBs will also be discussed, including applications to alleviate building pounding concerns when seismic joints are of limited size, many different configurations possible for retrofit construction, ideas for high rise applications, and other unique applications.
