The test results of five columns under cyclic bending-shear, cyclic pure torsion, and at various levels of combined cyclic bending and torsion respectively are presented in this paper. Based on the test results, it is concluded that the flexural as well as torsional capacity is decreased due to the effect of combined loading and there is also a change in the failure mode and deformation characteristics. |

Raymond Schnell, Talley Metals Technology, Inc.; and Michael Bergmann, NY DOT |
In 1937, the Progreso Port Authority, in the Port of Progreso, Yucatan, Mexico, began construction of a bridge. The uniqueness of this bridge was that it used stainless reinforcing rebar, AISI Type 304, due to the aggressive chloride environment of the saltwater where this bridge was built. Almost 70 years later, this bridge is still standing, and being used daily. |

Arthur Dinitz and Michael Stenko, Tramspo Industrues Inc. |
Because of the critical nature of the Woodrow Wilson Memorial Bridge to the U.S. Capital commuter and North South Interstate I95 commerce and travel traffic, an accelerated construction technique using precast deck panels was used for the deck replacement. The roadway panels were 44 feet wide (full roadway width) and 10 to 12 long, precast transversely post-tensioned light weight concrete. Because of the high traffic volume on the structure, traffic in both directions was transferred to one side, one lane in each direction nightly from 8:00pm to 6:00am. |

The development of a new generation of concrete: high strength/high performance concrete, self-consolidating concrete, light weight high performance concrete or light weight self-consolidating concrete, opened an interesting perspective to a new approach for progress in concrete bridge technology. This paper presents some of the results from a broader study dealing with early-age properties of lightweight self-consolidating concrete. |

Influence Of Additions In The Mechanical Properties Of Self-Compacting Concrete |
Janaina Araujo, Andre Geyer, Alexandre Castro and Moacir Andrade, Universidade Federal de Goias - Brazil |
To take care of its properties in fresh state, self-compacting concrete (SCC) demands a high powder content in its composition, about 450 kg/m³. The quarry dust, resultant material of the coarse aggregate production, appear as an economic and sustainable alternative in the development of the SCC. Using the mix design for SCC developed by Tutikian a study for evaluation of the SCC mechanical properties was done, where natural sand had been partially replaced by quarry - micaschist and granite - and cement for silica fume and metakaolin. |

Electrically Conductive Concrete for Infrastructure Applications |
Sherif Yehia, Ikhlas Abdel Qader, Vijay Meganathan and Osama Abudayyeh, Western Michigan University |
Electrically conductive concrete is a cementitious admixture, which can attain stable and high electrical conductivity when connected to a power source. This material was originally developed for deicing applications to utilize the heat that can be generated due to the electrical resistance and impedance of the mix. A modified mix was developed and being tested to evaluate its mechanical and electrical properties. This mix will be used for bridge deck deicing application in Calhoun county, MI. |

FRP Wrapping of Concrete Bridge Piers for Improved Durability |
Lisa Spainhour and Isaac Wooton, FAMU-FSU College of Engineering; Nur Yazdani, University of Texas at Arlington |
The service life and effectiveness of FRP repair and strengthening techniques when applied to concrete in corrosive marine environments is still not well understood. This paper presents the results of an experimental study on the corrosion performance of embedded steel reinforcement in cylindrical reinforced concrete specimens with 13 different surface treatment options. |

Control and Repair of Pretensioned Concrete Girders |
Christie Hasenkamp, Christopher Tuan and Maher Tadros, University of Nebraska-Lincoln; and Sameh Badie, George Washington University |
Recent developments of high performance concrete, increasing amounts of prestressing, and increasing use of deep girders have resulted in increasing popularity of precast pretensioned concrete girders in bridge construction. These developments have contributed to increasing end zone cracking. This paper summarizes the results of an ongoing research project sponsored by the National Cooperative Highway Research Program (NCHRP) Research Project 18-14 to study and develop possible causes, design, repair, and acceptance criteria for cracking. The paper will also give a summary of the results of a comprehensive survey of users of pretens |
