Structural Analysis
__________________________________________________________________________________ 1.1 INTRODUCTION The word structure describes much of what is seen in nature. Living plants, from the frailest of ferns to the most rugged of trees, possess a structural form consistent with their needs. Insects and animals play a more active role in building the structures that they need, e.g. the delicate web of the spider, etc. Humans, too, are builders of structures; but more than that, they are conceivers and designers. When the structures of humans began to reflect their ability to conceive and design them as well as to construct them, structural engineering was born, and it has grown in sophistication as it has endeavoured to meet the demands of humanity.

Determinate Beams A beam is defined as a structural member predominantly subjected to bending moment. In this chapter, only beams of symmetrical section, the centroidal axis of
