Abstract
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 .
