STRUCTURAL DETAILING OF A REINFORCED CONCRETE STRUCTURE – DUPLEX BUILDING FOR MR INNOCENT I. AZUOBU
IN NO 12 UGO – DAN STREETAZUIYIOKWU ABAKALIKI
PREFACE
In structural detailing, the project is initiated by the structural Engineer. The Architectural drawings are prepared by the Archived to the required scale and specification given to him by the client.
The Structural Engineer designs the structural framework of the building and specification required such as slab, beam, column and foundation.
For proper clarification and understanding, the structure is broken down into us component parts and detailed, keeping in mind the design consideration. Structural detailing is the transformation of the works of the Structural Engineer into working drawing for the builders to use without any cumber some.
The methods, symbols and notations used are standardized for uniformity despite the multi–diversity nature of the construction industry. The standard method of measurement notations of detailing a building should be understood before carrying the exercise.
            The purpose of their written account is to present a starlight forward introduction to the basic standard method in detailing reinforce concrete structure and their component parts. Here a structural detailing of three bedroom duplex has been hosen as  the project. Both the Architectural work and the Civil Engineering work have been completed. The subject matter has been arranged so that chapter 1 – 4 covers the description of basic material and engineering design specification while the last chapter covers the actual detailing of the components. All these details are shown in plan, elevation and section.

INTRODUCTION
The work in the construction industry involves the client, the Architect, the Engineer, the quantity surveyor and the builders. A structural project is initiated by the Engineer (Civil Engineer).
The process of designing begins with the Engineers appreciation of the client’s requirements. After the specification given to the Engineer by Architect according to the requirement of the client, the Engineer develops different structure scheme from the Architect plan and designed load, which will help him to know the axils load and neutral axis where the structure is liable to settle and develops sagging or hogging due t o improper use of rein for cement bar. Having considered the use of material and erection methods and then comes up with the final work of full structural analysis and detailed design.
Structural detailing can be defined as the process by which the design Ota structural system is drafted in a form that a builder can use for construction for easy establishment.
Also structural drawing is the principle means by which the designer communicates his requirements in a clear and unambiguous manner to the builder.
This project outlines the important components and basic techniques and methods required for structural detailing of a reinforced concrete duplex.
The structural drawing is simple to interpret, dimensions are clear. Bar bending schedules showing now the reinforcement bars are to be bend a real so provided. This is essential to the quantity survey or cost estimates of the project and to the steel to supply and also to the iron bender to determine the bends dimension.
A summary of design specifications, information and structural consideration a re provided standard scales and abbreviation are used to ensure the uniformity. The structural elements, beans, column, slabs, foundations have been detailed and shown in plans, elevations and sections.
It is therefore believed that this project will fulfill its requirements and serve its purpose of guiding the reader through the process of basic structural detailing.
