Abstract

This article analyzes the influence of link length on the behavior of eccentrically braced steel frames, considering link length and the number of stories as variables. The structural systems, designed according to AISC 360-22 and NEC-2015, were evaluated using nonlinear dynamic time-history analysis with three seismic records and nonlinear static pushover analysis. The results show that link length significantly affects stiffness, energy dissipation, and force distribution. Short links provide higher stiffness and better drift control but generate greater internal forces; intermediate links achieve a balance between stiffness and load capacity, while long links improve seismic energy distribution at the expense of lower initial stiffness. These findings highlight the importance of optimizing link length to enhance the seismic performance of these structures.
