• The procedure starts with the abutment stiffness that is calculated as ratio of the abutment capacity and an initial estimate of the earthquake-induced deformation. The analysis is repeated by updating abutment stiffness to reflect the abutment deformation calculated in the previous iteration until the abutment deformation at end of an iteration cycle… CONTINUE READING
