ABSTRACT

Abstract In this paper a method for designing moment resisting frames failing in global mode is presented. It is based on the application of the kinematic theorem of the plastic collapse. The beam section properties are assumed to be known quantities, as they are designed in order to resist vertical loads. The unknowns of the design problem are the column sections. They are determined by means of design conditions expressing that the kinematically admissible multiplier of the horizontal forces corresponding to the global mechanism has to be the smallest among all kinematically admissible multipliers.
