My column design in RCDC failed in flexure(joint) and some in shear.. how to redesign it? appreciate your help. thank yoy.
Hello,
You can right click on the failed column and select the redesign option.
Then you can change different inputs for that section. For flexure failure you can try with increased percentage of reinforcement. For shear failure try increasing grade of concrete. If that does not satisfy the criteria, try increasing the size of the section.
