The proposed light-frame structure comprises steel columns for vertical loads and an innovative bracing system to efficiently resist seismic actions. This seismic force resisting system consists of a light timber frame braced with an Oriented Strand Board (OSB) sheet and an external technoprene plaster-infilled slab. Steel brackets are used as foundation and floor connections. Experimental cycl...

BACKGROUND CONTEXT Pronounced kyphosis of the thoracolumbar junction is a common orthopedic problem in adolescents and may require prolonged bracing therapy or correction spondylodesis. PURPOSE To describe a case where a kyphotic deformity was related to gynecological instead of spine pathology. STUDY DESIGN Case report. METHODS A 17-year-old girl presented with a structural hyperkyphosis...

Buckling-Restrained Braced Frame system(BRBFs) are a new type of steel seismic-load-resisting system that has found use in several countries because of its efficiency and its promise of seismic performance far superior to that of conventional braced frames. The system is addressed in the 2005 edition of the AISC Seismic Provisions for Structural Steel Buildings, also a set of design provisions ...

Passive control methods can be utilized to build earthquake resistant structures, and also to strengthen the vulnerable ones. In this paper, we studied the effect of this system in increasing the ductility and energy dissipation and also modeled the behavior of this type of eccentric bracing, and compared the hysteresis diagram of the modeled samples with the laboratory samples. We studied seve...

The medial collateral ligament (MCL) and the posterior oblique ligament (POL) are the main static valgus restraints of the knee.Most isolated medial injuries can be treated with bracing and early knee motion.Combined MCL and ACL (anterior cruciate ligament) injuries can be managed with bracing of the knee followed by a delayed reconstruction of the ACL.Residual medial laxity may be addressed at...

CLINICAL SCENARIO Ankle injuries constitute a large number of injuries sustained by adolescent athletes participating in high school athletics. Prophylactic ankle bracing may be an effective and efficient method to reduce the incidence of ankle injuries in adolescent athletes in the secondary-school setting. CLINICAL QUESTION Do prophylactic ankle braces reduce the incidence of acute ankle in...

The medial collateral ligament (MCL) is commonly injured in the setting of anterior cruciate ligament (ACL) injuries. Because the MCL has better healing capacity than the ACL, the general perception is that MCL injuries can be treated conservatively. Treating these injuries conservatively, however, can lead to residual valgus laxity. Furthermore, it delays time to surgery, which prevents acute ...
