A utility-based method of design for serviceability is developed and applied to a case study of office floor deflections. Structural design for serviceability is reviewed and surveys of engineers and building developers yield information on the occurrence and evaluation of serviceability problems. A probabilistic utility-based formulation of the serviceability design problem is presented, and design optimization is related to pseudo-limit states and associated serviceability indices appropriate to 'single point' design checks. The case study includes the review and adaptation of stochastic load models, the development of a load-response model to account for random spatial variations of structural properties, and detailed numerical modelling of time-dependent deflections of non-prestressed reinforced-concrete slabs. Results indicate that, for a broad class of serviceability problems, approximately optimal deterministic design criteria are related, in a simple manner, to the 'damage' threshold and a design load associated with a serviceability index of roughly 3.5.
