Developing and Validating New Bolted End-Plate Moment Connection Configurations
This research has been aimed to introduce larger moment carrying connections for any type of buildings, in particular the metal building industry. A total of four connection configurations, namely eight-bolt extended four wide, eight-bolt extended stiffened, six bolt flush unstiffened and twelve …

Development and Validation of a Twelve Bolt Extended Stiffened End-Plate Moment Connection
Three end-plate moment connection configurations are prequalified for special moment frames for seismic applications in AISC 358-10. The eight bolt extended stiffened connection is the strongest of the three configurations, but it can only develop approximately 30 percent of currently available …

Unified Design of Extended End-Plate Moment Connections Subject to Cyclic Loading
… design procedures for eight extended end-plate moment connection configurations subject to cyclic/seismic loading. In addition, the suitability of extended end-plate moment connections for use in seismic force resisting moment frames was investigated. Eleven full-scale cyclic and nine monotonic …

Evaluating the Effect of Decking Fasteners on the Seismic Behavior of Steel Moment Frame Plastic Hinge Regions
A series of full-scale beam-to-column moment connection tests were completed to determine the effects of powder actuated fasteners (PAF) and puddle welds on the seismic behavior of steel moment connections. In seismic regions, PAF are currently prohibited in the connection region (referred to as …

Evaluation of Extended End-Plate Moment Connections Under Seismic Loading
… was conducted to study the extended end-plate moment connections subjected to cyclic loading. Seven specimens representing three end-plate moment connection configurations commonly used in the pre-engineered building industry were used. The connections were designed using yield-line theory to …

A Case Study on Medium and High Rise Timber Buildings
… concept for a 19-story glulam building, with a moment resisting frame as a structural system. The building is numerically modeled and exposed to real wind loads obtained from the Boundary layer wind tunnel laboratory (BLWTL). The moment connection shared characteristics based on tests conducted …

Seismic performance of an I-girder to inverted-T bent cap bridge connection
… regarding the seismic response and overall moment capacity of precast I-girder to inverted-T bent cap bridge connections for seismic applications. The current design practice, as outlined by Caltrans' Seismic Design Criteria, assumes that the connection between the precast I-girders and the …

Experimental and Analytical Investigation of the Shear Strength of Unstiffened Tapered Steel Members
… to bending in similar proportion to the bending moments, more economical structures can be obtained. The beam and column connection, or knee area, is generally subject to the greatest bending moments. It is therefore comprised of the deepest sections of the tapered members, which also possess the …

Innovative Self-Centering Connection for CCFT Composite Columns
… filled steel tubes. However, most common connection configurations for circular concrete filled tubes are not economic in the US market due to (a) the desire of designers to use only fully restrained connections and its associated (b) high cost of fabrication and field welding. Research …

Application of Ductile Yield Link in Glulam Moment Connections
Wood beam-column connections have traditionally been designed as simple shear connections, ignoring their potential moment capacity. A major reason for not utilizing such moment connections is linked to the brittle limit states that wood components exhibit. The purpose of this research was to …

Behavior and performance of steel moment-framed buildings subject to dynamic column loss scenarios
… research employed a set of two prototype steel moment-framed buildings to study dynamic ground-level column-loss scenarios for a variety of column locations within the structures. One building contained three stories while the other had ten. Both were intended to be representative of typical …

Effect of Continuity Plate Eccentricity on the Performance of Welded Beam-to-Column Connections
<p>Beam-to-column connections in structural steel buildings may have varying degrees of rotational restraint and varying degrees of moment transfer. In fully restrained moment connections, shear is typically transferred through the beam web, while the moment is mostly transferred through the beam …

Investigation of Single and Two Bolt Connections Perpendicular to Grain in Laminated Veneer Lumber
Bolted connection with perpendicular to grain loading has been considered as a high priority research area by Smith and Foliente (2002), for the advancement of the load resistance factor design (LRFD) of connections. The results obtained from the experimental testing of this research will provide …
