This study presents a new all-steel Buckling-Restrained Brace (BRB) named Coplanar Dual Core (CDC) BRB, that consists of rectangular cross-sectional core divided into two coplanar yielding lateral bands, whose movements are constrained by an external restrainer (ER) and internal (IR). In contrast with the traditional BRB dog-bone shaped core, CDC-BRB has advantage can be easily extracted inspec...

BACKGROUND The knee joint is vulnerable to various injuries and degenerative conditions, potentially leading to functional instability. Usual treatments involve knee orthoses to support the joint. However, the level of mechanical action of these devices remains controversial despite high prescription and demand. METHODS The mechanical ability of three commercial hinged knee braces and one sle...

All of the low back braces available today are fabricated to provide anteriorly or posteriorly directed forces . None accomplishes satisfactory immobilization, and, in fact, braces with a high thoraco-lumbar purchase area increase lumbosacral motion (1) . Attempts to improve the lumbar immobilization by applying increased abdominal pressure are useful to a limited degree, as in the Williams bra...

Abstract Steel braces are widely used to stabilize steel structures forming horizontal or vertical truss structures; however, their relatively poor buckling behaviour is often lead overdesigned structures. Induction Heat (IH) treatment technology a novel contactless material transformation process effectively strengthen local areas of sections. Utilizing IH increase the strength middle length b...

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.
