Abstract:
This paper discusses the relative importance of the factors causing deflections, including effects not specifically included in the codes, such as differential shrinkage and temperature stresses, and cracking due to temporary loads during construction. The performance of an actual structure where deflections were much greater than predicted by the application of standard code provisions is examined and the contribution of each of the deflection factors is analysed. Recommendations are given for the assessment of deflections in practice, and examples are given of how the use of modern computer methods allows detailed non-linear analyses to be applied in the design office.
