| Abstract | A new innovative brace, “cam-grip” device, also named as “compression-free energy dissipation device” (CFD), is introduced in this paper. After that this device is used in a compression-free energy dissipation brace (CFB). CFB is composed of “cam-grip device”, which function is to clamp the sacrificial bar under tensile loading and release the bar under compressive loading, and sacrificial steel bar, for energy dissipation by yielding under tensile loading. The subassemblage test of CFB was conducted under different cyclic loading to study the behavior. A repeatable and stable hysteresis loop was observed and the brace worked well as expected. After that, the CFB was modelled in Perform 3D by using the inelastic bar. A comparative study between six-story BRB building and CFB building was done by nonlinear time history analysis on two-dimensional structure in Perform 3D. From this result, it can be concluded that the CFB is not appropriate to use in chevron braced configuration due to the uplift force on beam. If the diagonal braced system is used, a similar result were found out between these two buildings |
