Design and Full-Scale Testing of a Cast Steel Yielding Brace System in a Braced Frame

Development of an innovative metallic damper for concentrically braced frame systems based on experimental and analytical studies

“…Numerous passive metallic dampers, as a device indirectly added to brace members, have been developed to improve the hysteretic behavior of the CBF systems. For instance, Steel plate‐based dampers: ADAS, [ 13,14 ] TADAS, [ 15,16 ] rhombic, [ 17 ] single round‐hole, [ 18 ] X‐shaped, [ 19 ] slit, [ 20,21 ] comb‐teeth, [ 22 ] parabolic, [ 22,23 ] prebent strips [ 24 ] and curved steel dampers, [ 25 ] and shear damper. [ 26,27 ] These dampers exhibit suitable seismic performance; however, they require high‐quality manufacturing. Dampers made as links: EBF, [ 28–30 ] vertical shear links, [ 22,23,31,32 ] shear damper, [ 33,34 ] and knee braces, [ 35,36 ] U‐shaped steel, [ 37 ] torsional beams, [ 38 ] tapered cantilevers, [ 39 ] and tapered tube dampers.…”

An Innovative Steel Damper with a Flexural and Shear–Flexural Mechanism to Enhance the CBF System Behavior: An Experimental and Numerical Study

“…Numerous metallic dampers have been developed to improve the hysteretic behavior of CBFs such as ADAS [11][12][13], TADAS [14][15][16][17][18], buckling_restrained brace (BRB) [19][20][21][22][23][24][25][26], ring damper [27][28][29], shear damper [30][31][32][33][34][35][36][37][38][39][40][41][42], J_damper [43], crawler damper [44], and cushion damper [45]. These dampers act as a ductile seismic fuse during an earthquake.…”

Sensitivity Analysis of Behavior of Simple Trapezoidal Steel Plates to Introduce a New Yielding Damper

“…The tested specimens also revealed a completely stable hysteresis loop curve before tooth fracture while tolerating significant cumulative displacement. Gray et al [21][22][23][24] introduced a yielding damper using parallel triangular pieces from 2012 to 2017. During several years of research, he built his damper by casting.…”
