“…The pre-tension load can be even negative to simulate initial looseness of the TOB. No post-yield stiffness is considered for the derived PHM as earlier experimental results indicated that tension-only element experience very little strain hardening [25]. This is mainly due to the fact that tensile plastic strains would be distributed along the full length (or at least a long portion) of the tension-only element and are well below strain hardening threshold.…”

“…Obtained results, however, were not persuasive and no noticeable improvement has been observed [18,[20][21][22][23]. Recently Tamai and Takamatsu [25] proposed a non-compression rod bracing with a special washer/wedge connection. In their proposed connection, the wedge slides between the beveled washer and this would prevent rod buckling.…”

“…The MBF series exhibited the most effective resistance to lateral drift, even though it was relatively low-weight [21]. A method to inhibit buckling failure of the braces has been reported, which uses non-compression braces installed with sliding equipment at the brace connection [22].…”

Cross-bracing (X-bracing) is one of the most popular methods of seismic retrofitting, and has been shown to significantly increase the structural stiffness and strength of buildings. Conventional steel X-bracing methods typically exhibit brittle failure at the connection between the brace and the building, or buckling failure of the braces. This study investigated the structural properties of a new type of non-compression X-bracing system using carbon fiber composite cable (CFCC). This non-compression X-bracing system uses CFCC bracing and bolt connections between structural members and the terminal fixer of the CFCC, instead of conventional steel bracing. The aim is to overcome the brittle and buckling failures that can occur at the connection and bracings with conventional steel X-bracing methods. We carried out cyclic loading tests, and the maximum load carrying capacity and deformation were investigated, as well as hysteresis in the lateral load-drift relations. The test results revealed that the CFCC X-bracing system installed in reinforced concrete frames enhanced the strength markedly, and buckling failure of the bracing was not observed.

“…For preventing buckling occurrence in the bracing members, buckling-restrained braces have been investigated [3]. A non-compression brace [4] and a dissipative bracing system [5] have been proposed to improve the seismic resistance with bracing. Some researchers have examined the application of braces to retrofitting [6,7].…”
