Structural/Reinforcement Detailing of a Single Storey Residential Building With Retaining Wall

Structural/Reinforcement Detailing of a Single Storey Residential Building With Retaining Wall

PREFACE

This is the presentation of information on the structural reinforcement detailing of concrete members. Structural detailing is a branch of structural work that transposes the idea or works of a structural engineer into working drawing or easy utilization in the building construction works. Working drawings are produced by 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, good interaction and contractors are required. The methods, states, 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.

STRUCTURAL SYMBOLS

The abbreviations recommended for structural detailing work are as follows.
a. R.C. – Reinforced concrete
drg – drawing
hor – horizontal
vest – vertical
dia – diameter
fdn – formation
conc – concrete
col – column
b. Type of reinforcement
R – Mild steel bars
Y – High yield bars
c. Comments relating to reinforcement
C – centre line
B – Bottom
T – Top
c/c – centre to centre

CHAPTER ONE

INTRODUCTION

Before a designer can relate his requirements dearly in the construction industry, a drawing is to be prepared; this is because the drawing serves as a general means of communication. Thus, drawing is adopted mostly, then other means of communication in engineering sectors.

A structured engineer mostly engages himself in designs on the construction of structures. Like roads, bridges, railways, dams, buildings and other public works.

The structural engineer makes initial designs, which are usually freehand sketches of the work. These sketches are used to make a clean and neat working drawing, which will be used by the builder of the contractor after approval for construction by the authorities involved.

The contributions of a detailer are highly significant to the construction process, for a well-detailed drawing is a good medium of reducing the risks of building collapses and avoiding delays arising from doubts and too frequent clarifications.

This project shows the methods and techniques needed for the detailing of reinforced concrete structures.
