ABSTRACT

In Chapter 5 the analysis of sections under given prestress force and applied loading was considered. The general problem, however, is that of design: given a structure with overall geometry and applied loading, what size of member is required and what are the details of the prestressing force and tendon profile? A trial-and-error approach could be used, the test being whether the serviceability and ultimate limit state requirements are met at all sections under all possible load combinations. This might prove to be a very lengthy process, however, and a more systematic approach would clearly be advantageous.
