El-Haddad, O. Ramadan, A. Bazaraa] A fracture mechanics model has been implemented in the stiffness matrix method to analyze skeletal structures resting on elastic foundations and containing cracks at superstructure and substructure elements. Stiffness matrices for cracked superstructure and substructure elements have been developed based on fracture mechanics techniques and the stiffness matrix method. The present model has been applied to investigate effects of crack size and location, type of loading, soil subgrade modulus, foundation rigidity, and geometry of the structure on the behaviour of cracked structures taking into consideration the soil-structure interaction effect.
