Behaviours of steel connections with unfitted stiffeners
Steel beam-to-column connections are fundamental to the structural integrity and safety of steel-framed buildings. A critical issue arises when gaps exist between stiffeners and connected elements, referred to as unfitted stiffeners, which introduce uncertainties in the load-bearing capacity and …

A Model for Prediction of Fracture Initiation in Finite Element Analysis of Bolted Steel Connections
… of fracture initiation in bolted structural steel connections using damage mechanics. A material failure envelope has previously been developed for aluminum extrusions using the IDS (instability, ductile, and shear) criterion. The IDS criterion is a damage mechanics based model for defining …

Strength characterization of wood to wood connections using stress field analysis
… option. However, current practice favors steel connections for wood structures. Wood to wood connections offer a solution to the minimization of steel connections. While some wood-only connections are referenced in timber codes, small modifications to these designs as well as a multitude …

Welding information system--design, operations, methods
… following three main topics. •Knowledge Base on Steel Metallurgy and Welding; •Analysis and Design Methods for Welded Steel Connections; •Design Requirements of Welds. This includes the considerations of different types of welds and joints and a thorough review of welding history and basic …

Time history analysis of axial forces (Pass Through Forces) at joints in a braced frame
… value of pass through force at a node, the steel connections will not be overdesigned, resulting in cost savings. In this thesis, we analyse multiple bracing configurations for a typical steel frame under different load combinations in order to find a procedure for computing pass through …

Rehabilitation of Longitudinal Joints in Double-Tee Girder Bridges
… bridge girders consists of discrete welded steel connections. Wehbe et al. (2016) showed that this longitudinal joint detailing is insufficient for fatigue, service, and strength loading, thereby significantly reducing the lifespan of these type of bridges. Currently, there are more than 700 …

Structural Mechanics Characterization of Steel Intermeshed Connections
… presents the efforts to develop a new class of steel connection named the “Intermeshed Connection” for gravity load resistance in frame structures. The thesis investigates the performance of the connection system using physical testing and numerical simulation, as well as methods for its design. …

Buckling-Restrained Braced Frame Connection Design and Testing
<p>As typically designed, the beam-column-brace connections of buckling-restrained braced steel frames have undesirable failure modes that compromise the integrity and performance of the frames and are costly to repair. To decrease the time and resources needed to repair the frames following an …

Behavior and modeling of partially restrained beam-girder connections
Beams in a typical steel framed floor design are assumed to have pinned supports for purposes of design. In reality, the connections between the beams and girders in a steel framed floor system are not pinned. The design bending moments and deflections of the attached beam could be reduced if the …
