The design and analysis of indeterminate frames and beams are important problems encountered by all structural engineers. With modern computer programs, analysis is not a difficult problem. Design is more complex and less amenable to programming. For efficient design, something between the following two extremes is needed:

  • The first intuitive approximation of the structural design engineer, without any additional information, and
  • A complex computer program where, of necessity, the original programmer has made general decisions/assumptions which seriously impact the diverse design criteria for which it is used, thereby constraining those who use the program.

This course is designed to assist structural engineers from all fields - civil to aeronautical - in developing initial design concepts. This is accomplished by determining an idealized optimum section property distribution for each of the most critical loading conditions. Even though, for many large structures encountered by civil engineers, it is impractical to vary the section properties continuously in accordance with the idealized optimum, it is very helpful to know what that idealized distribution is, so that it can be approximated within the limits of practicality.

Because the design of Optimum Beams - considered in this course - is a special case of the general theory, "Optimum Design of Indeterminate Frames", the general theory is briefly covered in this course. The student is assumed to be familiar with basic strength analysis theory and elementary calculus.
