Predictive equations for bolted connections
… for the study of this project. For single line bolted connections, the value of the eccentricity coefficient is determined by several independent variables: NR (number of rows in the bolted connection), B (distance between two adjacent bolts in a vertical column), Xo (horizontal distance from …

Fretting Fatigue Characterization of Steel Bolted Connections
… small amplitudes at the same time. Slip-critical bolted connections are commonly used in repetitive loading applications and are susceptible to fretting fatigue failure. Among the many factors that can affect the fretting fatigue life of the bolted connections, bolt preload and surface finish are …

Constitutive Modeling of Friction in Bolted Connections
Bolted joints are ubiquitous in mechanical engineering, requiring accurate models to optimize designs. However, the exact nature of frictional contact between components is unknown and poses a significant challenge to modeling the nonlinear vibration of assemblies. This thesis applies empirical and …

Bolted Flange Alternatives for Moment -Resisting Connections
These alternative connections eliminated the backing bar, used high quality shop weld, and reduced the high stress and strain demand on the weld. Therefore, the failure of the bottom flange weld did not occur. However, for connections using the bottom girder flange component only, the inelastic …

Inelastic Cyclic Behavior of Bolted Flange Plate Connections
All of the BFP connections reached 5.0% total rotation and 3.0% plastic rotation without significant strength degradation. The participation of BFP connection components in the inelastic behavior depends upon the relative strength and strain hardening of BFP connection components. The slip behavior …

An investigation of FRP reinforced glulam bolted connections
… reinforcement in Laminated Veneer Lumber (LVL) bolted connections under double shear loading. The FRP investigated consists of uniaxial carbon fibers embedded in a two-part epoxy. Sixteen sample wood connections were tested. Eight samples were reinforced with FRP such that the carbon fibers were …

Parametric analysis of bolted flange connections of circular monopoles.
… study involved the parametric analysis of bolted flange connections of eighteen different circular monopoles. The parameters considered were the number of bolts (8, 6, and 4) and thickness of flange plate [25.4 mm (1.0 in.), 19.05 mm (0.75 in.) and 12.7 mm (0.50 in.)]. These were analyzed …

Behavior of bolted connections during and after a fire
… temperature must be understood. Floor beams and bolted connections were studied with both experimental and analytical methods in this research program, which provide useful information on the strength of bolted connection at elevated temperature. Shear strength of A325 and A490 high strength …

A Comprehensive Integrity Monitoring System for Bolted Flange Connections
Bolted flange connections are commonly utilized to link pressure vessels and pipeline systems. Although there exists a series of design codes and standards to specify the design of flange joints, multiple adverse factors, such as unexpected loads and excessively high pressures and temperatures, can …

Bolted flanged connections made of fiber reinforced plastic materials
… shells, little work has been done to investigate bolted flanged connections. The ASME Boiler and Pressure Vessel Code or the codes of other industrialized countries do not include specific rules for the design of FRP bolted flanged connections. Up to now, the only work done on fiber reinforced …

Two novel techniques to study multiple bolted wood connection behavior
… were evaluated for studying multiple-bolted wood connection behavior. The instrumented shear bolts output an electronic signal proportional to the shear forces transmitted through the bolt in a double-shear connection during loading. The digital image correlation method combines …

Experimental Investigation of Group Action Factor for Bolted Wood Connections
… the 5% offset yield and capacity of single-shear bolted wood connections loaded parallel to grain. The single and multiple-bolt connections tested represent common connection geometries used in wood construction in the United States. The results of both monotonic and cyclic loading of connections …

Experimental and Numerical Study on Bolted/Bonded Composite Joints for Aircraft
Bolted and bonded joining technologies in composite structures have been widely studied since the 1970s. Although every technology has advantages and disadvantages, bonded joint technology has the potential to reduce the weight and manufacturing cost of advanced aircraft structures. However, bolted …
