Abstract

For computing moment magnification and then design R/C columns with rectangular or circular sections, there is a number of procedural steps and equations provided by ultimate strength design method according to ACI-Code. The large number of equations and fork of solution steps causes a lot of confusion and boredom for the students or designers. Having consulted the most common and authoritative textbooks that dealt with design of reinforced concrete structures as well as my long experience in teaching reinforced concrete material. I have concluded that the novel flowchart according to ACI 318-2011 has more effect to give beginner engineering students speed to achieve design steps by less time and effort. This study focuses on compression members within braced (nonsway) or unbraced (sway) frames which have rectangular or circular sections subjected to axial compression loads and uniaxial moment. Finally, the author has enabled to draw a simplified flowchart to track steps of moment magnification easily and conveniently by using SI units.
