Calculation of deflections of slim floor beams
Serviceability calculations of slim floor systems is a controversial issue due to the uncertainties associated with concrete cracking, the stiffness of the shear connection and the mechanical interaction between concrete, structural and reinforcing steel. EN 1994‐1‐1 does not include any provisions on the design of slim floor beams. In this paper a method, compatible to the ζ‐method of EN 1992‐1‐1, for the determination of deflections in slim floor beams is proposed. Recommendations for considering the flexibility of the shear connection and the influence of creep and shrinkage are also given.
