Deflection Control Two methods are given in the ACI Code for controlling deflections for beams and one-way slabs not supporting or attached to partitions or other construction likely to be damaged by large deflections. In this section, a discussion of the serviceability limitations for the case of FRP RC beams is made and a formulation to assess the serviceability requirements is suggested. The figure below shows a part plan of a composite floor. Deflection The wording now clarifies that the deflection of a runway beam due to the safe working load is to be measured relative to its supports. Beam and slab deflection needs to control as serviceability requirements. Chapter 16 - Deflections of Beams Reading: Chapter 16 — Pages 577-583 16-1 Introduction When designing a beam and structures in general, we need to consider serviceability requirements as well as its strength requirements. to meet the requirements of today’s demanding customers.

For a case where r = 0.6 and [psi] = 0.2, the service moment due to strength requirements is [M.sub.s] = 0.48[M.sub.u], but because serviceability requirements normally govern the design of FRP RC members, this strength moment is rarely attained, and the service moment is lower. • The curvature limit of 0.005/d may satisfy the serviceability requirements. The serviceability requirements limit the maximum deflection that is allowed in a structural element subjected to external loading. Serviceability design criteria are important for people's comfort, as well as the integrity of separation walls, façades and other non-load-bearing elements and finishes.
