Structural Analysis and Design For Concrete Buildings

Courses Syllabus

Course Description

Concrete is everywhere! In pavements, building structures, foundations, motorways/roads, overpasses, parking structures, brick/block walls and bases for gates, fences poles and many more. Concrete is used more than any other man-made material on the planet. It has been said that instead of naming our era “The Nuclear Age” it Should be named “The Concrete Age” as almost all of our modern lifestyle and constructions Depend on this material.

This five-day course covers the manufacturing, designing and maintaining of concrete. It includes the details about ingredients and its quality, quantity and effect on the final product of concrete. Concrete designing, its Specifications, standards and codes and the concrete mix design is discussed in detail along with various procedures and precautions on field manufacturing of concrete. The defects, investigations and the remedial measures and repairs are covered in detail and the modern concepts like ready mix concrete, precast and prestressed concrete and their applications are also reviewed.

The basics from ingredients of concrete to repair and maintenance is covered throughout the workshop and would be very useful to every technician who works with concrete. The methods of design are discussed here which can help the engineers, architects and designers to design the most effective final product of concrete.
