Abstract:
Presents American and European design provisions for the control of deflections. Both minimum and computed versus allowable deflections of CEB-FIP Model Code (MC 1990) and ACI Code (ACI 318-89) are considered. The methods in both codes for predicting deflections and applying span/depth-thickness ratio are evaluated in design examples. Based on the simplified method for computing the long term deflection, no significant difference is found between the codes.
