Moment formulation for random eigenvalue problems in beams

摘要

This paper proposes a moment formulation model to handle eccentric load imperfections in beams on elastic foundation taking into consideration the randomness of imperfections. An alternative approach to the secant formula to capture the effects of load imperfections is described. The study demonstrates eccentricity is the most detrimental form of structural imperfections and that it aggressively and adversely interacts with other imperfections.
