A barrier system includes first and second barrier segments connected to one another. The connection between the segments includes a pair of wedge-shaped connectors disposed between angled faces formed at the opposing ends of the segments. Elastic pads are sandwiched between the respective segment faces and connectors.

Barrier system

A crash impact attenuator system for deployment in front of a structure includes a rail and a plurality of diaphragms initially disposed in spaced relation along the length of the rail. Each of the plurality of diaphragms moves along the rail, so that when a front end of the crash attenuator system receives an impact force from a vehicle, a first one of the diaphragms moves rearwardly along the rail and impacts a second one of the diaphragms so that both the first and second diaphragms move further rearwardly along the rail, this process continuing with additional ones of the diaphragms until the impact forces have been fully attenuated. A tearing member on the crash attenuator system engages material forming a side or fender panel of the crash attenuator system, the tearing member tearing material forming the side panel to attenuate the impact force.

Crash impact attenuator systems and methods

A structural assembly may include a first prefabricated structural element having a first angled face at an end of the first prefabricated structural element; a second prefabricated structural element having a second angled face at an end of the second prefabricated structural element, the end of the second precast barrier segment connected to the end of the first prefabricated structural element; and a coupling assembly connecting the first angled face of the first prefabricated structural element to the second angled face of the second prefabricated structural element. The coupling assembly provides shear and moment continuity across the first and second prefabricated structural elements. This allows for a variable gap due to manufacturing tolerances, construction tolerances, and/or expansion or contraction.
