Abstract Tall buildings have unique seismic challenges, particularly the P-delta effect. This can cause an increase in loads on certain parts of structure, leading to potential instability or collapse. The solution is use buckling restrained bracing (BRB) systems, which improve lateral strength structure and control present study aimed determine effectiveness various brace configurations reduci...

This paper presents a design application of the proposed generalized response spectrum analysis (GRSA)-based seismic optimization method to large metal spatial structure (constructed in Japan) where rigid diaphragm assumption is not available and displacement responses are disproportionally distributed story. It also discusses optimal mixed placement capacity distribution buckling-restrained br...

Within multiple design challenges, the lateral torsional buckling (LTB) analysis and stability check of structural glass members is a well-known issue for design. Typical examples can be found not only in slabs with slender bracing but also facades walls, where fins are used to brace vertical panels against input pressures. Design loads such as wind suction give place possible LTB LR at tension...

BACKGROUND Lateral knee osteoarthritis is notably common after anterior cruciate ligament reconstruction (ACLR). While valgus bracing has been investigated as an intervention for medial knee osteoarthritis (OA), little is known about the effectiveness of varus bracing for lateral knee OA after ACLR. PURPOSE To determine the immediate effects of a varus unloader knee brace on gait biomechanics...

OBJECTIVES The purpose of this retrospective study was to investigate whether treatment with a carbon brace (CMCR) stops the progression of idiopathic scoliosis in children and adolescents affected by combined or thoraco-lumbar scoliosis. METHOD We compared clinical features (hump and vital capacity) and radiolographic data (Cobb angle, sacral slope, lumbar lordosis and thoracic kyphosis) at ...

BACKGROUND Factors influencing clinical course of brace treatment apply to adolescent idiopathic scoliosis (AIS) patients remain unclear. By making clear them, we may select suitable patients for brace treatment and alleviate overtreatment. The purpose of this study was to explore predictive factors of Osaka Medical College (OMC) brace treatment for AIS patients in accordance with the modified ...

STUDY DESIGN Level 4 retrospective review. PURPOSE Brace treatment is the standard nonoperative treatment for adolescent idiopathic scoliosis (AIS). Rotation correction is also important, because AIS involves a rotation deformity. The purpose of this study was to evaluate the impact of rotation correction after Osaka Medical College (OMC) brace treatment on clinical outcomes in AIS. OVERVIE...

BACKGROUND A need exists for a functional anterior cruciate ligament (ACL) brace that dynamically supports the knee joint to match the angle-dependent forces of a native ACL, especially in the early postoperative period. PURPOSE/HYPOTHESIS The purpose of this study was to quantify the posteriorly directed external forces applied to the anterior proximal tibia by both a static and a dynamic fo...

STUDY DESIGN In this prospective study, we measured the pad pressures of the Milwaukee brace in adolescent hyperkyphosis treatment. PURPOSE We evaluated the skin-brace interface forces exerted by the main pads of the Milwaukee brace. OVERVIEW OF LITERATURE A fundamental factor associated with brace effectiveness in spinal deformity is pad force adjustment. However, few studies have evaluate...

Due to low stiffness of braces after yielding, the structures with buckling-restrained braces (BRBs) experience high residual drifts during an earthquake, which can be intensified by aftershocks and causes considerable damages to structures. Also, due to poor distribution of stiffness, this problem is exacerbated for irregular structures. Recently, the yielding brace system (YBS) has been intro...
