OBJECTIVE To access the acceptability of Steenbeek brace by children undergoing clubfoot correction and their parents to ensure long-term compliance. METHODS The cross-sectional study was conducted at the Indus Hospital, Karachi from October 2013 to March 2014. A trained researcher interviewed the person primarily responsible for bracing the child using a pre-coded questionnaire. Modified Ort...

Design and detailing requirements of seismic provisions for concentrically braced frames ~CBF! were specified based on the premise that bracing members with low KL /r and b / t will have superior seismic performance. However, relatively few tests investigate the cyclic behavior of CBF. It is legitimate to question whether the compression member of CBF plays as significant a role as what has bee...

Helmet-mounted systems (HMS), such as night vision goggles and helmet-mounted displays, are designed to enhance pilot performance. Using HMS, however, may also affect pilot safety by increasing the potential for neck injury during ejection due to the increase in dynamic forces generated in the cervical spine as a result of the change in helmet inertial properties. Pilot bracing techniques may a...

In this paper the authors analysed four single-layered braced barrel vaults with different types of bracing. Each vault covered area 20 m × 28 and was made from steel hollow sections. The static-strength analyses structures were conducted using Autodesk Robot Structural Analysis program, taking into account self-weight, glass cover, snow load wind load. case load, pressure perpendicular to long...

To explore the difference in impact of transverse bracing on seismic effect through concrete-filled steel tube arch bridges with non-isolated and earthquake-isolated, nine earthquake-isolated structural models under different cross-bracing arrangements were established, Elcentro waves selected. The internal force, displacement, velocity, absolute acceleration, relative separation ribs each mode...

Selection of wind force resisting system is an important decision in the design tall buildings, especially for those located hurricane prone regions. Rigid frames, shear walls, braced framed tube, bundled tube and hybrid are common structural forms used to resist lateral forces produced due wind. Cables have a great potential be as element. Cable stayed hanging bridges guyed towers applications...
