Passively damped bracing systems in steel frames, in which the conventional materials of the joint are replaced
by high damping viscoelastic materials, have the potential of being effective practical means for passive vibration control
of dynamically loaded civil engineering structures. However, this potential can be realized only if the associated structural
penalties are reduced within acceptable limits. This paper describes a rational methodology for the development of an advanced
joining type for structural systems capable of providing enhanced dissipation of vibration energy without serious
penalties in strength, stiffness, or weight characteristics. One such configuration is that of a V-type bracing system with a
joint which provides a beneficial deformation coupling between the direction of load transfer and less critical offset directions.
A comprehensive parametric study has been carried out in order to establish design guidelines for favorable tradeoffs
between damping benefits and the associated stiffness and strength penalties in an FRP V-type joint. The results are
compared with the corresponding tradeoffs for a V-type joint made from conventional materials.
