Abstract Shear dampers are known as famous seismic passive energy devices due to their suitable performance against loading improve the behavior of Concentrically Braced Frames (CBFs). The CBF system suffers from low ductility its compression member's susceptibility buckling. By adding shear directly diagonal element members CBF, prevent bucking and system. Although pertain high dissipation cap...

experimental tests were performed to study the seismic behavior and performance ofmodified steel chevron braced frame systems, which incorporate a vertical slotted connection(vsc) detail between the top of the braces and the floor beam above. the vsc detail isintended to prevent vertical load transfer to the beam and limit brace forces to thecompressive resistance of the members. full-scale qua...
