چکیده مقاله
In general, the main expectation from Lateral force resisting systems is to provide high lateral strength, sufficient ductility and higher energy dissipation during an earthquake In recent years, researchers have consistently strived to introduce innovative energy dissipation systems that overcome the limitations of existing seismic resisting systems while providing acceptable seismic behavior This study compares an innovative shear resisting frame SRF with vertical and horizontal elliptical openings in the link beam web and recommends the shear resisting frame with elliptical openings as an efficient seismic resisting system based on behavioral analysis In this research, the shear resisting frame with horizontal and vertical elliptical openings is subjected to pushover and cyclic analysis using ABAQUS finite element FE software Additionally, to further investigate and optimize performance, a parametric study is conducted on the shear resisting frame with horizontal elliptical openings Based on the results obtained, the shear resisting frame with vertical elliptical openings shows more stable hysteresis loops, higher seismic coefficients, and better ductility and energy dissipation compared to the horizontal elliptical openings Considering the shear energy dissipation mechanism and suitable seismic coefficients with stable cycles, it can be stated that the shear resisting frame with horizontal and vertical elliptical openings demonstrates acceptable behavior as a lateral force resisting system
