After earthquakes, repair and replacement of structural elements is time consuming and expensive. This new truss system contains several diagonal elements designed to absorb seismic energy and yield at prescribed levels. Standard moment frame design requires 100% visual inspection and ultrasonic testing which is eliminated when using the Tru-Frame system. Since all Tru-Frame connections are single pass fillet welds and tension control bolts, they can be visually inspected any time after completion without need for additional testing. This allows subsequent trades to start their work sooner.
