Abstract:
Reviews the interdependence of rate and method of construction and design code provisions on the safety and serviceability of flat slab-type structures, and identifies areas of research need. Typical construction procedure involves casting a new slab onto forms that are supported on one or more previously cast floors. The loads occurring on the supporting slabs during construction, determined by the construction schedules, are large. That these construction loads are applied to slabs that have not achieved their design strength is an added complication
