Loads,hat can act on a structure, and then goes on to explain how the loads carried by individual structural members are calculated. This vital stage in the design process can be quite tricky — particularly if it is necessary to analyse an old existing structure.

Combined axial and bending stresses, a combination of axial force and bending. This chapter is concerned with how the resulting stresses are combined. Consideration is given to both an elastic serviceability approach (i.e. what are the stresses under working loads?) and an ultimate design approach (i.e. is there an adequate safety fac

Deflection,it state of collapse. However, one serviceability limit state which can influence the size of structural members is deflection. It is particularly a problem with long span beams, cantilevers and members made from material with low elastic modulus such as timber or fibre composites.

to realistic examples and emphasis is placed on understanding and developing a physical feel for the way that structures work. The necessary mathematics is explained and illustrated by numerous examples.

Pin-jointed trusses,and practical solutions in most cases. It is only with very large or repetitive structures that a more complex computer analysis is really justified. Initially we shall be restricting the analysis to . trusses, which means that all of the members and loads lie in one flat plane.
