The web of plate girders in bridges are usually reinforced by welded transverse stiffeners in order to improve their shear capacity.Due to problems associated with field welding and fatigue, welded stiffeners are not suitable for retrofitting existing bridges. Bolted stiffeners are a practical alternative for strengthening girders that are expected to experience shear stress in excess of their ...

Mechanical joints, such as the bolted shear lap joint considered here, are ubiquitous in engineered structures, which realize vibration damping as well as load transfer from them. However, the prediction of the energydissipation characteristics of such joints remains a challenging problem. A cubic relationship between energy dissipated and load magnitude is often assumed in classical joint dyna...

The behavior of the web panel zone has a direct effect on cyclic performance steel moment connections. While mechanisms failure are known under load, little is about bidirectional loads in bolted Using experimental tests and calibrated numerical models, this research evaluated unidirectional loads. results showed that load can modify stress strain distribution zone. Moreover, increasing width-t...

Bolt-ball joints are widely adopted in grid structures due to their high installation accuracy and short construction period. Since the bolt is inside joint, it challenging evaluate its health status from outside structure. A finite-element plane-truss structure model, based on actual structure, was constructed investigate influence of rod’s preload overall stiffness bearing capacity Moreover, ...

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 ...

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...
