PREFACE
This is the presentation of an information on the structural reinforcement detailing of concrete members. Structural detailing is a branch of structural work that transposes the idea or works of222 a structural engineer into working drawing or easy utilization in the building construction works. Working drawing are produced an engineer for easy use by the contractors.
The processes detailing put in place was in conjunction with the recommendations of the concrete society and the institute of structural engineers. In building construction a good interaction and contractors are required. The methods, scates, symbols and notations must be standardized and understood by all parties in a project to minimize risks and communication hindrances.
A structure is broken down into identifiable elements for detailing work like bean column, slab etc which enables the different detailing aspects to be fully addressed and understood.
