Columns and beams of the moment-resisting frames with high ductility level are automatically checked and reported according to Table 9.3.


  • The cross-sections used for the columns and beams of the moment-resisting frames must not undergo local buckling and must be compact enough to provide certain ductility capacity.

  • Local buckling must be prevented for horizontal load-bearing system elements to perform sufficient plastic deformation under earthquake effects. For this purpose, the width-to-thickness ratios of elements must be satisfied according to the conditions given in Table 9.3.

  • Since the plastic deformation capacity of systems with high ductility level should be relatively higher, the limit values ​​are smaller.
