PERFORMANCE OF AN INNOVATIVE BEAM-TO-COLUMN/BRACE-TO-FRAME CONNECTION UNDER MONOTONIC AND CYCLIC SHEAR LOADING
A new general structural connection with the ability to connect various structural elements of any material to one another was invented. In contrary to all existing connections, it has a high shear deformation capacity which can be exploited in various circumstances including as a bracing-to-frame connection in concentrically-braced frames to reduce their high elastic stiffness. In this way, their natural frequencies decrease which in turn lead to a decline in their earthquake induced forces. This high shear deformation capacity which can be accompanied by high strength and stiffness is the source for its high energy dissipation capacity. The results of a number of monotonic as well as cyclic shear tests on various specimens of this connection with different dimensions are reported here. The monotonic tests results clearly show the high shear deformation capacity of this connection which was accompanied with high shear strength and stiffness. The hysteresis loops obtained through cyclic tests, which were stable and well-rounded, however, show the ability of this connection to dissipate energy in an efficient manner.
