Abstract: The objective of this research was to investigate the inelastic behavior of built-up shear links through the use of large-scale experiments and detailed numerical analyses. The purpose of the large-scale experiments was to determine the deformation capacity, maximum resistance and ultimate failure mode of built-up shear links by applying incrementally increasing cyclic plastic deformations. Based on the results of the experimental and numerical research, built-up shear links were shown to be effective hysteretic energy dissipators. The importance of estimating the link overstrength is illustrated and design recommendations are defined. Illustrations, tables, and references are included.
