This paper compares and analyzes the differences in fire performance between concrete-based Buckling-Restrained Braces (BRBs) and all-steel BRBs. Concrete-based BRBs achieve thermal insulation through the low thermal conductivity and high specific heat capacity of the concrete shell, with a fire resistance duration of over 2 hours. However, there is a risk of steel core exposure due to concrete spalling. All-steel BRBs are vulnerable to high temperatures due to the high thermal conductivity of steel, with a fire resistance duration of less than 1 hour without protection, requiring reliance on external protective measures such as fire-resistant coatings, but they offer better repairability and adaptability. The study indicates that concrete-based BRBs are suitable for scenarios with high fire protection requirements, while all-steel BRBs have advantages in seismic-prone areas and scenarios requiring rapid installation. In the future, it is necessary to further optimize the fire-resistant coating technology for all-steel BRBs.
