Numerical Investigation on the Behavior of Bent Shear Panel Damper on Eccentrically Braced Composite Frames
In modern buildings, seismic loading is an added important factor to account in safe structural design. Seismic dissipation systems are utilized to protect critical components in the structure from the energy released during earthquakes. Metallic yield dampers are low-cost components providing energy dissipation through yielding. Steel dampers have indeed gained significant attention and research due to their stable hysteretic behaviour, as well as their ease of availability and construction compared to other metals. Steel possesses excellent mechanical properties, such as high strength, ductility, and toughness, making it an attractive material for structural damping applications. Bent shear panel dampers (BSPD) are shear panel dampers (SPD) with bent in the middle and connected to the web of the composite beam in the frame to overcome the drawbacks of traditional SPDs a relatively new addition to the yielding metallic damper, with the properties of easy assembly and low cost. The bent panel can help maintain the lateral stiffness and energy dissipation capability of the frame. In the present study behavior of BSPD is to be evaluated using finite element software ANSYS Workbench to enhance the ductility and thereby to improve the energy dissipation capacity. The failure modes, strength and overall behavior of the specimens need to be studied. Some parameters which include effect of slits and the effect of low yield materials mainly aluminum. Number of slits is a crucial parameter that defines the stiffness and compactness. Slits proves to be an innovative energy dissipation technique which not only reduces cost but also gains sufficient ductility by plastic hinge formation at the slits. Slit improves the ductile behavior and energy dissipation by more than 100%.low yield material aluminum improves the energy dissipation capacity and improves the ductility of the material slightly and shows high improvement in stiffness. Perforations lessen elastic stiffness and yield strength in comparison to unperforated specimens.
