The theory of structures is concerned with establishing an understanding of the behaviour of structures such as beams, columns, frames, plates and shells, when subjected to applied loads or other actions which have the effect of changing the state of stress and deformation of the structure. In this text, professor horne employs this method to explain the. In the elastic theory of bending, as discussed in previous chapters, the method of design has been to calculate the maximum stresses occurring, and to keep them within the limits of working stresses in tension and compression, the working stresses being obtained by dividing the yield or ultimate stress by a factor of safety. As the moment is increased, the plastic zones increase in depth, and, it is assumed that plastic yielding can occur at yield stress f y resulting in two stress blocks, one zone yielding in tension and one in compression.
