Basic Design of Reinforced and Prestressed Concrete

 

BASICS OF REINFORCED AND PRESTRESSED CONCRETE DESIGN

 Most Civil engineering or building projects require the construction of either a reinforced or prestressed concrete structure.  These are usually designed by specialists but must be committed to paper by draughtsmen, or interpreted on site by construction staff at all levels.  It is necessary for these technical or supervisory staff members to identify errors and omissions by having a basic knowledge of the design process.

 The starting point for the course is an analysis of determinate structures and indeterminate structures (by the method of coefficients) and the identification of stresses generated in the structure by applied loads.   A set of specially made plastic models will be used to illustrate the deformation and stability of structures under load, and have proved to be invaluable in ensuring the understanding of students in the past.

 Properties of the materials used, i.e. concrete, reinforcement and cables will be given with a guide to materials specification for the avoidance of cracks and deflections etc.  All formulae derived and used will be identical to those given in the South African code of concrete design SANS 10100 Parts 1 and 2, with an emphasis on structural performance based on selection and placement of materials.

 The approach to design is a logical, step-by-step process with many examples of the design of beams, columns and slabs done by students in groups, who are later provided with detailed calculations for the structural elements.  A comprehensive set of notes will be given to all students which follows a well-illustrated power-point presentation.  Prior knowledge by students will dictate the volume of instructional material that can be covered in two days but more complex design principles are well-covered in the notes to be taken away.

 All technical staff in Civil Engineering and building will benefit by attending the course, whether it be as a refresher or as an introduction to the principles of the design of concrete elements.  More experienced designers would benefit from the emphasis placed on material properties and specification.
