Precast Hybrid Moment Frame

Built for Stress

The Precast Hybrid Moment Frame (PHMF) system represents the latest seismic-resistance technology and is deemed to be one of the best performing lateral resistance systems available today.

The ductile frame is designed to handle significant seismic drift while experiencing minimal damage due to its post-tensioned, self-righting mechanism. Truly a “resilient” structure.

Superior Seismic Performance

The system offers the benefits of prefabricated building systems, the durability and mass-building benefits of concrete construction, and a seismic performance superior to all other conventional systems due to its unique ability to self-right after a major seismic event, enabling immediate re-occupancy of the structure.

Superior seismic performance in an earthquake compared to conventionally framed steel and concrete structures. The ductile frame is designed to handle significant seismic drift while experiencing minimal damage due to its post-tensioned, self-righting mechanism for a truly “resilient” structure.

Taking Seismic Systems Beyond Yielding

Most seismic systems dissipate energy through yielding, and it is not unusual for a building to lean after a major earthquake. As a unique feature, the elastic, unbonded post-tensioning used in the PHMF system is designed to overcome yielding in the frame and pull it back to a righted position.

Exterior facing elements of the system can be architecturally finished as part of the production process – offering additional material efficiency whereby structural elements function as architectural elements as well.
