A path to more versatile code provisions for slab deflection control

An assessment of the methods codes ACI 318 and Eurocode 2 is performed to establish a minimum slenderness for reinforced concrete slabs, which simplified method controlling deflection slabs. This by comparing these with each other two further that have inspired, among others, Australian standard structures. The variables evaluated include those most influence control (span, load allowable deflection). study cases spans range from 6 m (20 ft) 12 (40 loads 5 kN/m2 (104 lb/ft2) 15 (313 lb/ft2). results reveal some key advantages shortcomings provisions. Suggestions are provided improve current provisions codes. Methods not too complicated but more refined can help code become versatile. aim this work minimise potential problems caused designing excessively thick slabs (heavy pollutant) or slender (too deformable).
