ABSTRACT
The analytical method described in this book precludes the use of the standard flexure and interaction formula in predicting the yield capacity of steel tubular sections. The types of tubular sections considered are steel pipes and square and rectangular tubing. The analytical method is based on the application of basic mathematics and the strength of materials approach. The stress-strain plot of the steel material is known to be linear up to its yield stress. From this property we can write the equations of the forces that can be developed on a given steel tube section using calculus. The author has demonstrated this procedure in papers presented at the ISEC-01, ISEC-02, and SEMC2001 international conferences and ASCE 2004 Structures Congress as well as in his book
Analytical Method in Reinforced Concrete
(2004). The same approach will be utilized in this book.
