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 recent years, seismic design of structures has been undergoing significant changes due to increasing demand for optimization and minimizing the level of damage and reducing the cost of structural repairs. Development of analytical methods and remarkable improvements of computer performance have been among the factors which influenced the design of structures. A lot of research has been condu...

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.

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 (...
