Connections in Steel Structures VI Proceedings of the Sixth International Workshop

This book presents the proceedings of the Sixth International Workshop on Connections in Steel Structures. The workshop was held at the Westin Michigan Avenue Chicago in Chicago, Illinois, USA during the period 23-25 June, 2008 under the auspices of the American Institute of Steel Construction and the European Convention for Constructional Steelwork.
The five preceding international workshops were held in Cachan, France, in 1987; Pittsburgh, Pennsylvania, USA in 1991; Trento, Italy, in 1995; Roanoke, Virginia, USA, in 2000; and in Amsterdam, The Netherlands, in 2004. Proceedings for the five preceding workshops were published by Elsevier Applied Science Publishers (1988), the American Institute of Steel Construction (1992), Pergamon/Elsevier Science (1996), the American Institute of Steel Construction (2002) and Bouwen met Staal, the Netherlands (2005). The American Institute of Steel Construction (AISC) and the European Convention for Constructional Steel (ECCS) supported the idea of holding a sixth workshop, thus making it possible. Financial support for the workshop was provided by the American Institute of Steel Construction, Nucor-Yamato Steel, Gerdau Ameristeel, and Steel Dynamics.
The American Institute of Steel Construction was the official host of this workshop that was held in their home city. Outstanding work by the staff of AISC made the workshop possible. The contributions of Katy Preston, Elizabeth Robelet, and Ashley Melvin to the planning and on-site arrangements are particularly appreciated. Areti Carter and Janet Cummins took charge of the technical details and the preparation of these proceedings for which we are all very grateful. In addition, the participation of the individuals who served as session chairs contributed significantly to the smooth running of all three days of the workshop.
Finally, the support and technical contributions of the 71 participants from 19 countries who presented 56 technical papers must be acknowledged. Without their commitment to research, design, and construction of structural steel connections worldwide, none of this would have been possible. It is expected that the continued commitment of these participants and others to come in the future, will result in another successful workshop in Timisoara, Romania in 2012.

AISC 303-10 Code of Standard Practice for Steel Buildings and Bridges

This Code sets forth criteria for the trade practices involved in steel buildings, bridges, and other structures, where other structures are defined as those structures designed, fabricated, and erected in a manner similar to buildings, with building-like vertical and lateral load resisting elements. In the absence of specific instructions to the contrary in the contract documents, the trade practices that are defined in this Code shall govern the fabrication and erection of structural steel.
Commentary:
The practices defined in this Code are the commonly accepted standards of custom and usage for structural steel fabrication and erection, which generally represent the most efficient approach. This Code is not intended to define a professional standard of care for the owners designated representative for design, change the duties and responsibilities of the owner, contractor, architect or structural engineer of record from those set forth in the contract documents, or assign to the owner, architect or structural engineer of record any duty or authority to undertake responsibility inconsistent with the provisions of the contract documents. This Code is not applicable to steel joists or metal building systems, which are addressed by SJI and MBMA, respectively.

Steel-Free Hybrid Reinforcement System for Concrete Bridge Deck

Use of nonferrous fiber-reinforced polymer (FRP) reinforcement bars (rebars) offers one promising alternative to mitigating the corrosion problem in steel reinforced concrete bridge decks. Resistance to chloride-ion driven corrosion, high tensile strength, nonconductive property and lightweight characteristics make FRP rebars attractive. However, there are design challenges in the use of FRP reinforcement for concrete including concerns about structural ductility, low stiffness, and questions about their fatigue response and long-term durability. The report presents results from a three-year collaborative investigation conducted by the University of Missouri-Columbia (UMC) and the University of Missouri-Rolla (UMR). Details of the investigation, results and discussions from static and fatigue studies are presented including experimental programs on bond, flexural ductility, accelerated durability, and full-scale slab tests. Based on the results from this investigation, the use of a hybrid reinforced concrete deck slab is recommended for field implementation. The hybrid reinforcement comprises a combination of GFRP and CFRP continuous reinforcing bars with the concrete matrix also reinforced with 0.5% volume fraction of 2-in. long fibrillated polypropylene fibers. A working stress based flexural design procedure with mandatory check for ultimate capacity and failure mode is recommended
