Existing literature suggests that substituting mineral aggregates with tire-derived aggregate (TDA) in concrete increases the ductility and toughness of at cost lowering its strength stiffness. Hence, TDA has applications dynamic systems, such as lateral resisting frames sustaining seismic loads. This study investigated application buckling-restrained braced (BRBFs). Buckling-restrained brace (...

The friction behavior of mortar–polymer–steel debonding interfaces was experimentally investigated to support numerical simulation buckling-restrained braces (BRBs). Characteristic contact and slip demands were developed using two-dimensional Abaqus models inform a full-scale test program. A stabilized dynamic coefficient 0.065 observed for reciprocating two-way sliding at the reference bearing...

In this paper, we propose an assembled self-centering buckling-restrained brace (ASCBRB), which eliminates the residual drift of structures after a major horizontal displacement. The ASCBRB also represents advanced device for partial replacement damaged parts brace. Four groups prestressed disk springs and metal yielding core plate were used to improve resilience energy dissipation brace, respe...

To rapidly repair the damaged buckling-restrained brace serving as energy absorption member during earthquake, assembled method of wrapping component with FRP cloth is proposed. In this research, a series cyclic tests on six (ABRB) wrapped three kinds FRPs (carbon fiber, glass fiber and basalt fiber) were performed. The tested results show that all specimens excellent hysteretic performance sim...

In order to realize the buckling-restrained brace (BRB) with high energy absorption performance, it is important prevent premature local bulging failure of restraining part. this study, strength BRB resist part considered be minimum value steel plate considering influence effect filling materials and bearing materials. Local prevented by larger than force acting in out-of-plane direction.
