In regions with high seismic risk, a precast hybrid moment frame (PHMF) is an optimum system for combining cladding and structure. The PHMF comprises high-quality precast column and beam elements, produced under factory-controlled conditions, that are connected using traditional construction methods and materials. The system is self-righting—the elastic, unbonded post-tensioning is designed to overcome yielding in the frame and pull the building back to a righted position.
