Validation of the European Yield Model for Nailed Connections
Recent changes in National Design Specification for Wood Construction (NDS) connection design methods make it necessary to validate the European yield model (EYM) for nails. Test values...
Behavior of Tall Frame Combining Rigid and Semi-Rigid Connections
In this paper, the applicability of the mixed use of rigid and semi-rigid connections in the tall frame is discussed. It is tried. for 4-bay 8-storey frame to be numerically analyzed for...
Cyclic Performance of Riveted Connections
As part of a larger experimental project on seismic performance of older steel frames, seven concrete-encased and unencased connections were tested. The specimens consisted of both riveted...
AWS versus AIJ Tubular K-Connection Design Rules
Among various existing design rules for circular tubular connections, the AWS rules are compared with the AIJ rules because of differences between the two. Subjects of discussion include...
Focusing on Fatigue
Properly designed and maintained bridges sometimes need repair for fatigue damage. Among the reasons may be that the bridge was designed before current fatigue design provisions, or initial...
Seismic Performance Behavior of Precast Concrete Beam-Column Joints
The experimental test program being conducted at the National Institute of Standards and Technology on 1/3-scale model precast concrete beam-to-column connections is summarized. The objective...
A Comparison of the Cyclic Performance of Bolted and Riveted Connections
As part of a larger project to investigate the performance of older steel frames, a comparative study of bolted and riveted T-stub connections was conducted. The study included connections...
