Hello everyone When the column stirrup tightening is done across the entire floor, it will help us in loading combinations, for example, will it help reduce the force on the axis? Secondly, what does the column main axis mean Thank you everyone, good work Regards..[/quote ] Hi, Stirrup provides resistance against shear force. The tightening conditions are given in TDY 2007 item 3.3.4. It has no effect on the design axial force and axial force capacity. The main axes of the column are the major and minor axis of the column. Column Reinforced Concrete dialog/End Force Diagrams can be viewed on the tab. Good work
