Results related to the study of six regular steel buildings structured with ductile concentrically braced frames of 10-, 14- and 18-stories are reported. Models were designed following a proposed capacity methodology for this structural system and were located in subzone IIIa of the Mexico's Federal District Code. Nonlinear analyses were performed in OpenSees considering the material overstrength through 292 certified laboratory coupon tests of steel samples available in the Mexican market.
