The treatment of design for deflection control in current practice is empirical, and relies largely on allowable computed deflections that were established on the basis of experience gained at a time when deflection control was not a critical issue in most cases. In this paper the current deterministic approach to deflection control is compared with design for safety, which is based on probability considerations.
