Beam on Elastic Foundation


The BEB+ program can be used to calculate elastically supported beams and one-way slabs based on the subgrade reaction modulus method in combination with the displacement method. The user can optionally select whether foundations and stiffness should be constant, linear or erratic. The foundation can be set to zero, either completely or in individual sections. In addition, tension spring failure can optionally be considered in the calculation. If the foundation is set to zero over the total beam, at least two supports are required. The user can add further rigid or elastic supports.
