Earthquakes during ground motions load structures a significant amount of displacement en-
ergy. By using energy-damping steel elements, it is possible to dissipate most of the earthquake-induced
energy in buildings. Within the scope of the study, a new energy dissipating steel damper model devel-
oped. The developed model was named as Energy Dissipating Steel Bean (EDSB). The strength and
behavior of steel beans with 3 mm, 5 mm, 8 mm and 18 mm thickness under the effect of shear were
investigated numerically by means of ANSYS program which can compute according to finite element
method. Shear force strengths, hysterical curves and energy dissipation values under the effect of cyclic
repetitive loads with displacement control were found according to the FEMA 461 specification. EDSB
dampers were subjected to an ultimate deformation of 250 mm during numerical studies using a struc-
tural steel material with a yield strength of 350 N/mm2 and tensile strength of 430 N/mm2. "Kinematic
hardening model" was chosen as the most suitable model for cyclic loading in the analyzes made in
ANSYS program. At the end of the study, findings such as average load strength, load-displacement
relationships, elastic stiffness, secant stiffness and effective stiffness were obtained. Thanks to these
findings, yield displacements, ductility and energy dissipation values of EDSBs of different thicknesses
were determined. It is predicted that if EDSB dampers are used in the future, major damages that may
occur in buildings under the effect of severe earthquakes can be prevented.
