This paper presents a general analysis on the shear stiffness of spine bracing systems of selective storage racks in the down-aisle direction. Unlike the architectural steel structure, the bearing capacity of bracing connection in the spine bracing systems of steel rack structure is weaker than that of bracing members. Firstly, destructive tests of spine bracing connection in single entry racks...
The utilization of orthotic devices for lumbar degenerative disease has been justified from both a prognostic and therapeutic perspective. As a prognostic tool, bracing is applied prior to surgery to determine if immobilization of the spine leads to symptomatic relief and thus justify the performance of a fusion. Since bracing does not eliminate motion, the validity of this assumption is questi...
“Cold-formed steel (CFS) stud walls” are innovative alternative for construction of walls in buildings. The main frames of CFS walls consist of a group of vertical members called “studs” which are hold by fasteners within two horizontal members called “tracks” at the upper and lower ends. One of the conventional ways for designing and analyzing of CFS stud walls under blast loading is to employ...
Background: Bracing treatment for adolescent idiopathic scoliosis is a commonly prescribed treatment for curvatures up to roughly 35°. Little data in the United States has been published concerning bracing treatment for larger curves, as surgical intervention is typically reserved for such cases. This study reports on the combined use of Boston bracing and a conservative manual therapy system f...
the objective of this review to be submitted in two independent parts, for steel frames and for rc frames, is to compare their structural performance with respect to the proposed n2-method, and so also of the consequent convenience of using pushover methodology for the seismic analysis of these structures. a preliminary investigation is presented on a pushover analysis used for the seismic perf...
Passively damped bracing systems in steel frames, in which the conventional materials of the joint are replaced by high damping viscoelastic materials, have the potential of being effective practical means for passive vibration control of dynamically loaded civil engineering structures. However, this potential can be realized only if the associated structural penalties are reduced within accept...
Abdominal bracing is often adopted in fitness and sports conditioning programs. However, there is little information on how muscular activities during the task differ among the muscle groups located in the trunk and from those during other trunk exercises. The present study aimed to quantify muscular activity levels during abdominal bracing with respect to muscle- and exercise-related differenc...
