Contrast: Unifying the Nuts and Bolts
The world is full of extremes and I enjoy studying the contrasts of these extremes. I am influenced by the soft and subtle, as well as the rough and unrefined. From printing on the most delicate of papers, to constructing objects from scrap metal and reclaimed barn wood, the pieces I produce are …

Beyond bolts : architectural details, construction, meaning
An architectural Detail is a small piece of the whole, yet it has the power to characterize and define the entire building. Details tell us what a building is; they are fundamental to the life and personality of a space. Additionally, the design of a simple connection can and should be indicative …

Reliability analysis of single-headed anchor bolts
… in current design criteria for anchor bolts subjected to tensile or shear loading is discussed with emphasis on the ACI, the PCI and the proposed Load and Resistance Factor Design (LRFD) equations. Available data from test results on the anchor bolts and welded studs were analyzed. …

Load transfer mechanism of fully grouted cable bolts.
Fully grouted cable bolts have been used in the mining industry for more than fifty years. However, failure of cable bolting systems still occurs in mine sites, as a result of insufficient load transfer between the rock mass and the cable bolt. Numerous research studies have been conducted to …

Destructive disassembly of bolts and screws using impact
Disassembly, the process of separating parts or components at the end of their useful life is complex due to a variety of fastener shapes and variability in their damage during use. As a natural solution, mechanical impact has been suggested as a cost-effective method for destructive disassembly of …

Performance of snug tight bolts in moment end-plate connections
… to study the behavior of snug tight ASTM A325 bolts in moment end-plate connections for use in single story buildings. Wind loading was deemed to be the critical loading on snug tight bolt, moment end-plate connections. A test loading sequence was established based on a statistical analysis of …

Effects of Head Size on the Performance of Twist-Off Bolts
… application of button-head type twist-off bolts. Currently, the Research Council on Structural Connections Specification (2000) removes the requirement for ASTM F436 washers (ASTM 2000a) under the bolt head of twist-off bolts where the head diameter equals or exceeds that of an ASTM F436 …

Some factors in the use of roof bolts for mine roof control
… transverse center-to-center distance between the bolts. 4. What stress should be applied to the bolt when installed. 5. How often should the bolt be retightened. This thesis will be an attempt to solve some of these problems.

The behaviour of composite beam-to-column flush end plate connections using blind bolts
… beam-to-column joints connected using blind bolts were tested under static and cyclic loading. The test results were used to obtain the load-displacement characteristics of the connection, failure modes and strain development. The test results demonstrated sufficient stiffness and strength of …

The Variability of Strains in Bolts and the Effect on Preload in Jointed Structure
… are the most common method used for tightening bolts; however, this method can cause a large amount of uncertainty in the resulting bolt preload. With the inability to determine the preload in bolted structures precisely, overdesign is necessary for bolts to meet safety requirements and prevent …

The NUTS and Bolts of Evaluations of the European Union:Exploring the Regional Dynamics of Public Perception
No longer an elite project, European integration is increasingly dependent on citizen support for the continued enforcement of current political systems as well as further integration effort. Europe’s regions are highly diverse and are a significant focus of European policymaking and budgeting. …

Analysis of the Behavior of Steel Silos Under Wind Loading (Buckling, Stiffeners, Corrugated Shell, Anchor Bolts)
This study deals with the linear elastic analysis and the linearized buckling analysis of steel silos under wind loading. In the first part, the wind loading pattern is established and the equivalent orthotropic rigidities of standard corrugated sheets are reviewed and, in some cases, new improved …

Analytical and experimental investigation of a flush moment end-plate connection with six bolts at the tension flange
An analytical and experimental investigation was conducted to study the six bolt flush moment end-plate connection configuration which is used in steel frame construction. The limit states of plate yielding and bolt fracture were analyzed using yield-line theory to predict endplate thicknesses and …

Two novel techniques to study multiple bolted wood connection behavior
Two novel techniques, instrumented shear bolts and digital image correlation, 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 …

Parametric analysis of bolted flange connections of 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 under stiffened and unstiffened conditions. Four, two and four stiffeners, 12.7 mm (0.50 in.) thick, were used …
