This article summarizes a numerical and mathematical comparison between filled
and hollow X-shape plates to develop a new steel energy dissipative damper for structures
protection of earthquakes. The plate is a weld from two ends. Energy is dissipa
ted through
flexural yielding when the plate is subjected to inelastic cyclic deformation. The
performance of the plate was verified by five models by software ABAQUS and plastic
mechanism analysis. Results showed that the plate exhibited stable hysteresis and dissipate
energy with excellent values. It is Important to say all dimensions of plates and quality of
steel are verified by international articles. This article's interest lies in studying the effect
of openings on plate's dissipation energy.
