CFVR7263 - Bending + Axial force design according to ACI 349 06
Design a reinforced concrete beam subjected to Bending + Axial force according to ACI 349 06
A fixed beam which has a rectangular reinforced concrete section is subjected to a list of axial forces and beding moments, in Z axis, from the CFVR7263.FM file
The aim of the example is to obtain the reinforcement factor according to ACI 349 06. A spiral reinforcement will be disposed
