The mechanical behavior of light steel framing (LSF) walls under horizontal (shear) loadings is reported and assessed in this paper. In total, an experimental program with twelve LSF (six monotonic six cyclic loading) was conducted, the main parameters investigated were (i) thickness (ii) material used as cladding (OSB, a plasterboard, sheet), (iii) spacing between fasteners (150 or 75 mm), (iv...

During the last two decades, attention of researchers has been focused on repairing and retrofitting concrete frames to make them more earthquake-resistant. Two methods have developed increase seismic resistance previously undamaged structures before they are subjected an earthquake. The first is through addition new structural members, such as steel braces second by selectively strengthening e...

Statistics of human losses and financial casualties induced progressive collapse, as one the new modern concepts in field civil engineering, have doubled importance having knowledge about this phenomenon strategies to reduce its effect. Progressive collapse starts with a local failure loss load-carrying capacity small portion structure spreads throughout from element element. These consecutive ...

Background The Lyon brace, devised by Stagnara in 1950, is commonly prescribed in many European countries, and is based on the three-point pressure system. The Lyon brace also applies derotational forces to the spine, with the main thoracic plate pushing the hump from the posterior convexity toward the anterior concavity of the scoliotic curve. Lyon bracing is considered to be an effective mean...

BACKGROUND Bracing could be efficacious, given good compliance and quality of braces. Recently the SOSORT Brace TREATMENT Management Guidelines (SBTMG) have highlighted the perceived importance of the professional teams surrounding braced patients. PURPOSE To verify the impact of a complete rehabilitation team in the adolescent patient with bracing. MATERIALS AND METHODS Design. Initial cro...

SUMMARY OF BACKGROUND DATA Adolescent idiopathic scoliosis can progress and affect the health related quality of life of the patients. Research shows that screening is effective in early detection, which allows for bracing and reduced surgical rates, and may save costs, but is still controversial from a health economic perspective. STUDY DESIGN Model based cost minimisation analysis using hos...
