Abstract

Eccentrically Braced Frames are increasingly used in the design and/or retrofit of new and existing buildings and bridges. Accordingly extensive research works in this area are undertaken worldwide. In this paper a new type of Eccentrically Braced Frames composed of two vertical links is introduced. In this regard Eccentrically Braced Frames with double vertical links (DV-EBFs) are first introduced, effective parameters on selection of vertical link length and its design criteria are then explained. To investigate seismic performance of this system, nonlinear analyses (material and geometric) under monotonic and cyclic loading were performed to verify seismic behavior and effects of length and number of stiffeners used in the vertical link. The results show adequate shear strength, ductility and stiffness especially in short links with enough stiffeners.
