Bolted connections are widely used in parallel plates and flanged joints to axially lock using the preload generated by tightening torque constrain radial movements of flanges surface friction between mating surfaces. The depends on micro-asperities surfaces; under influence vibrations other external loads, these asperities tend deform over time, resulting failure connection. Bondura expanding ...

APTA is a sponsor of the Decade, an international, multidisciplinary initiative to improve health-related quality of life for people with musculoskeletal disorders. A lthough some people in the medical community accept the premise that the sacroiliac joint (SIJ) can be a source of pain secondary to pathology (eg, spondyloarthropathy, infection, malignancy, fracture),1 whether SIJ dysfunction ex...

An analytical approximate solution is developed for predicting the thermal resistance of bolted joints between two square plates . of the same material but different thicknesses. The plates are assumed to have perfectly flat and smooth surfaces, and they are joined by a bolted connection at the center of the square, forming a concentric annular contact region at the interface. The entire surfac...

Abstract The yield resistance of a high strength bolted frictional joint is evaluated based on the designed net cross‐section area. Japanese Specifications for Highway Bridges specifies area could be increased by factor 1.1 in verification at Serviceability Limit State where bolts are placed grid arrangement. In design staggered arranged joint, width strip to deducted from transverse section ac...

In this study, the structural performance of joint construction method using aluminum sprayed plate in concrete was evaluated, and corrosion characteristics film mortar also evaluated. The rate high early stage after placing, but it decreased with passage embedding period. This due to products deposited on surface aluminum, which presumably suppression especially anodic reactions. evaluation, w...
