External installation of steel braces is an effective approach to increase the lateral load resistance moment-resisting frames. However, effects existence on robustness frames resist progressive collapse still not clear because little study has been carried out. To fill this gap, in paper, six multistory subframes (three bare and three braced frames) were fabricated tested. Test results indicat...

Abstract The ways of designing and building steel girder bridges with a composite concrete deck vary much between different parts the world. A bridge system twin I‐girders or concept multiple (more than two) girders can be used. design use details secondary systems also lot. In order to give horizontal stabilization distribute loads, bracing bracings are often Although not so common, used verti...

BACKGROUND The Lyon brace is commonly prescribed in many European countries to patients with thoracic curves and is based on the three-point pressure system. The purpose of this study was to evaluate the efficacy of Lyon bracing for the conservative treatment of adolescent females with idiopathic thoracic curves in a case series selected on the basis of the Scoliosis Research Society (SRS) Comm...

The seismic-resistant structure is required for the earthquake-hazard area. One of systems Concentrically Braced Frame (CBF), which was established to diminish seismic damage. At time implementation, CBF reduces horizontal deformations building so that failure as well heavy damage can be avoided. In CBF, brace energy dissipator, whose performance needs enhanced. This study discussed structural ...

1 During gait, the trunk and neck are believed to play an important role in dissipating the transmission 2 of forces from the ground to the head. This attenuation process is important to ensure head control is 3 maintained. The aim of the current study was to assess the impact of externally restricting the motion of 4 the trunk and/or neck segments on acceleration patterns of the upper body and...
