  • Concrete is an ancient material of construction, first used during the Roman Empire, which extended from about 20 B.C. to 200 A.D. The word concrete is derived from the Roman concretus, meaning to grow together. Although this early mixture was made with lime, cement, and a volcanic ash material called pozzolana, concrete today is a sophisticated material to which exotic constitutents can be added and, with computer-controlled batching, can produce a product capable of achieving 50,000 psi compressive strength....

  • In the following calculation procedures, the design of steel members is executed in accordance with the Specification for the Design, Fabrication and Erection of Structural Steel for Buildings of the American Institute of Steel Construction. This specification is presented in the AISC Manual of Steel Construction. Most allowable stresses are functions of the yield-point stress, denoted as Fy in the Manual. The appendix of the Specification presents the allowable stresses associated with each grade of structural steel together with tables intended to expedite the design.

  • Weathering steel is NYSDOT’s first choice for steel multi-girder bridges under most conditions. This decision has been made in part because of the cost savings that can be realized due to decreased painting and maintenance requirements. However, recent studies have shown that this may not always be the case. This presentation will discuss some situations where bridges with weathering steel are underperforming and whether or not the situation can be rectified for future applications.

  • Racking is constructed from steel components including upright frames, beams and decking. Special beam to column (upright) connections and bracing systems are utilised, in order to achieve a three dimensional steel ‘sway’ or ‘braced’ structure with “aisles” to enable order pickers, industrial trucks or stacker cranes to reach the storage positions. Although components are standardised they are only standard to each manufacturer. These components differ from traditional column and beam structures in the following regard.
