Evaluation of resultant plasticity and fiber beam-column elements for the simulation of the 3d nonlinear response of steel structures
Abstract eng: The paper compares three nonlinear beam-column elements for the simulation of the global and local response of steel frames with respect to their accuracy and computational efficiency under monotonic and cyclic loading. The first element is a concentrated plasticity element, the second is a fiber beam-column element with very fine discretization of a typical wide flange cross section, and the third is a fiber beam-column element with a proposed coarse section discretization that minimizes computational cost while ensuring very good accuracy of global and local response. The paper concludes with practical recommendations for the discretization of wide flange sections for different levels of accuracy of 2d and 3d hysteretic response.
