Deflections of Prestressed Concrete Beams. Fibre-reinforced concrete (FRC) has been used in numerous types of precast elements around the world, as has been shown that reductions in production costs and time can be obtained; however, there is little experience of this material in Uruguay. Therefore, our study analysed the feasibility of its utilisation in this country. This paper reports on the development of a simple analysis model, As FRP bars possess mechanical properties different from steel bars, including high tensile strength combined with low elastic modulus and elastic brittle stress–strain relationship, the analytical procedure developed for the design of concrete structures reinforced with steel bars is not necessarily applicable to those reinforced with FRP..

Furthermore, concrete shrink as it dries under ambient conditions. Tensile stresses occur when free shrinkage is restrained. The combination of high tensile stresses with low fracture resistance of concrete often results in cracking. This cracking reduces the durability of a concrete structure..

This report presents consolidated treatment of initial and time-dependent deflection of reinforced and prestressed concrete elements such as simple and continuous beams and one-way and two-way slab systems. It presents current engi-neering practice in design for control of deformation and Abstract. An analytical method for predicting shrinkage deformations in both cracked and uncracked states is discussed. The validity of this method was verified by conducting an experimental investigation in which deformations due to shrinkage were measured for more than 300 days in the laboratory.
