Reliability Consideration in Shakedown Analysis

Abstract:

Shakedown analysis for ductile rigid frames has shown that a structure can respond linearly at a higher elastic limit after it has experienced some plastic deformation. If the residual deformation is acceptably small, one can increase the loading limit of the structure. Although shakedown analysis is understood by many engineers, only deterministic analyses have been performed thus far. It is desirable to include the uncertain nature of load and resistance in the analyses. A reliability model describing the residual deflection process of a 2-span continuous beam is proposed here. The goal is to aid future design of ductile rigid frames and continuous beams, such as bridges, to achieve a reliability level consistent with its design objectives.
