Web-restrained braces (WRBs) utilize standard steel bar stock used for metal buildings.
Four WRB frame subassemblages were subjected to AISC 341–10 test protocol for BRBs.
Three different sizes of steel core plates were examined.
All specimens exhibited stable and repeatable behavior up to 2% story drift.
The 12.7-mm thick core plate specimens endured additional cycles at 1.5% story drift.
