Steel is perhaps the most used construction material in the USA for high-rise towers, industrial buildings, bridges and other structures. It competes with reinforced concrete in the US and rest of the world because of its many favorable characteristics including high strength, high stiffness, ductility and toughness, speed of erection, competitive cost, etc. Its use in the Middle East region has been mostly confined to industrial plants and warehouses. The rise in labor cost and the need for higher buildings will inevitably improve the competitive edge of steel in many instances in the near future.
Design of steel structures has widely been based on the Allowable Stress Design whether the AISC standards of the British BS449 standards are used. This situation has changed since the mid eighties, but old habits expire hard. Many designers and fabricators still use the old allowable stress techniques. The more recent LRFD code of the AISC and the limit state BS5950 offer more rational and economical procedures for the design of steel structures.
This course shall make reference to various codes old and new but is primarily based on the AISC-LRFD procedures, which are the recognized state of the art in design.
This short course is intended to overview modern procedures for the design and erection of structural steel buildings. The course may be attended by civil engineers involved in design, fabrication and supervision. Each participant may draw on the elements of the course that most complement his area of interest and practice. For those engineers with limited practical experience the course will provide ample illustration of real design and construction issues that may assist the designer to conceive of a structural steel system that is safe, economical and constructible.
For the veterans the advent of LRFD and plastic design as well as computer-assisted design shall be the elements of the course that they may be looking to benefit from the most.
The wide range of issues to be discussed, revolve around the use of structural steel in buildings. The examples to be used would vary from the typical one-story warehouse to the multistory frame to special systems such as space frames. Throughout the course, the instructor shall start from the basics to allow ensuring the full participation and comprehension of all attendants, bearing in mind variations in background from education to practice.
Who Should attend?
Any civil engineer with interest in learning about steel design may attend the course and benefit from it. As backgrounds may vary the instructor shall start from the basics and work his way towards more details and to practical applications. It is foreseen that individuals from the following backgrounds may attend:
- Design structural engineers
