Recently, buckling-restrained braces (BRBs) have been widely implemented as seismic load resistance systems in buildings to enhance their response against dynamic vibration. However, during catastrophic earthquakes, the steel core BRB devices fully yields, which causes lose its functionality. While incorporation of various filler materials, such new high-performance concretes, has potential per...

We investigated the immediate effects of a varus knee brace on knee symptoms and knee-joint biomechanics in an individual with predominant lateral tibiofemoral joint osteoarthritis (TFJOA) and valgus malalignment after anterior cruciate ligament (ACL) reconstruction. A varus unloader brace was prescribed to a 48-year-old male with predominant lateral radiographic and symptomatic TFJOA and valgu...

Ponseti clubfoot treatment has become more popular during the last decade because of its high initial correction rate. But the most common problem affecting the long-term successful outcome is relapse of the deformity. Non-compliance with Ponseti brace protocol is a major problem associated with relapse. Although more comfortable braces have been reported to improve the compliance, they all hav...

OBJECTIVE To evaluate the effects of wearing a functional knee brace and muscle fatigue on hamstring reflex time in subjects with anterior cruciate ligament (ACL) deficiency. DESIGN Repeated-measures clinical trial. SETTING Outpatient physical therapy department. PARTICIPANTS Sixteen subjects with ACL deficiency. INTERVENTION Subjects tested with and without a functional knee brace befo...

Brace is one of the most commonly used interventions to manage osteoporotic vertebral fracture. However, its authentic effectiveness remains unclear. The aim of this study was to investigate the efficacy of brace in patients with osteoporotic vertebral fractures. We conducted a literature review and meta-analysis following the guideline and handbook of the Cochrane collaboration. Ten published ...

Failure in cold-formed steel beams is generally initiated by one of three instabilities: local, distortional, or lateral-torsional buckling. For cold-formed steel joists, purlins, or girts, when the compression flange is not restrained by attachment to sheathing or paneling, distortional buckling may be the predominant failure mode. Experimental results on cold-formed steel beams with unrestrai...

Background: Bracing concepts in use today for the treatment of scoliosis include symmetric and asymmetric hard braces usually made of polyethylene (PE) and soft braces. The plaster cast method worldwide seems to be the most practiced technique for the construction of hard braces at the moment. CAD (Computer Aided Design) systems are available which allow brace adjustments without plaster. Anoth...

Natural frequencies, mode shapes and modal damping ratios must be estimated to assess subsea pipeline spans for vortex-induced vibrations (VIV) response direct wave loading. Several approximate solutions exist a linearly elastic pipe under constant axial force supported by springs beyond the span's shoulders. An exact analytical solution has only recently been published. That is used here in Ra...

Materials and methods 2 asymptomatic adults, with similar physical feature. They wear a thoracolumbar bivalve brace, made with the same protocol (using CAD CAM) for reproducibility. We design the braces according to the principles of the brace immobilization: a good grip on the waist and overall tightening supports on the abdomen, thorax and lumbar. We use the gait analysis system Vicon. To use...

Linear eigenvalue analysis of cracked cylindrical shells under combined internal pressure and axial compression is carried out to study the effect of crack type, size and orientation on the buckling behavior of cylindrical thin shells. Two types of crack are considered; through crack and thumbnail crack. Our calculations indicate that depending on the crack type, length, orientation and the int...
