Single spans are the minimum span based on moment, shear, <br />web crippling, or deflection. <br />2. Multiple spans indicate two or more equal and continuous spans <br />with span length measured support to support. <br />3. Web crippling check is based on 1" of bearing at end and interior <br />supports. <br />4. Multiple spans are the minimum span based on moment, shear, <br />web crippling, deflection, combined bending and shear, or <br />combined bending and web crippling. <br />5.
