The seismic-resistant structure is required for the earthquake-hazard area. One of systems Concentrically Braced Frame (CBF), which was established to diminish seismic damage. At time implementation, CBF reduces horizontal deformations building so that failure as well heavy damage can be avoided. In CBF, brace energy dissipator, whose performance needs enhanced. This study discussed structural several modified bracings obtain a better configuration due action, i.e., single bracing (BR1), double with batten plates (BR2), and lacings (BR3). All specimens were 600 mm in length. on principle replaceable bracing, means removed replaced by new bracing. Accordingly, connection between gusset plate constructed bolted connection. Experimental work carried out employing cyclic load considering yield displacement control (dy). magnitude gradually increased at rate 1 dy. During test, observations emphasized load-displacement parameter, from specimen's described revealed. results showed adding sectional area BR2 BR3 effectively escalated parameters, strength, stiffness, dissipation energy. Furthermore, lacing installation efficiency contributed higher cumulative than BR2.
