چکیده مقاله
In this article, the nonlinear behavior of the Multi Section Flexural Damper MSFD has been investigated This type of damper is constructed using conventional steel channel sections reinforced with steel plates Given that ductile behavior is recognized as the primary factor in energy absorption in these dampers, the use of multiple sections and reinforcing plates results in increased strength, ductility, and energy absorption compared to single section dampers To study the nonlinear behavior of the damper, 15 finite element models of this damper type, considering various section conditions and reinforcing plate thicknesses, were analyzed under cyclic loading Their general characteristics, including deformation capacity, hysteresis curve, stiffness, and energy absorption, were evaluated The results indicate that increasing the dimensions of the used sections enhances deformation capacity and energy absorption, but reduces strength and stiffness However, this reduction can be compensated by using appropriately sized reinforcing plates, which can also improve these properties
