Updates to the Building Code Requirements for Masonry Structures.
The 2022 TMS 402 Building Code Requirements for Masonry Structures added Appendix D for glass fiber reinforced polymer (GFRP) reinforced masonry. GFRP reinforcement is non-corrosive, non-conductive, and not thermally conductive, so there is no thermal bridging. Due to these properties, GFRP reinforcement is advantageous in the masonry near electromagnetic equipment, such as MRI rooms in hospitals and masonry walls near high-voltage cables and transformers in substations. Other applications include walls exposed to severe environments, such as in coastal construction, seawalls, and chemical plants. The lightweight nature of the GFRP bar, being one-fourth the steel weight, allows for production efficiencies for the contractor and health and safety benefits to workers.
