The Canadian Approach in the Design of Wood Structures: Conversion to Limit States Design
During the early 70's, the National Building Code of Canada (NBCC) established the principle that structural design be carried out using the limit states design (LSD) method. The technical...
Strength Variability of Wood Formwork Members
Failure of concrete formwork is one of the main causes of concrete construction failures. Among the main causes of formwork failure is inadequate strength. Currently there is no published...
LRFD Provisions for Wood Bridges
A project to develop a load and resistance factor design (LRFD) edition of the American Association of State Highway and Transportation Officials (AASHTO) Standard Specifications for Highway...
Development Length of Uncoated Prestressing Strand
The Federal Highway Administration is conducting ongoing research which investigates the development length of uncoated and epoxy coated prestressing strand in prestressed concrete members....
Construction of the Baytown Bridge, Houston
Connecting Baytown and LaPorte, the Baytown Bridge is a twin structure with four traffic lanes each. Its structure is designed as a cable-stayed bridge with concrete towers and composite...
Construction of the Clark Cable-Stayed Bridge at Alton, Illinois
The Clark Cable-Stayed Bridge crosses the Mississippi River at Alton, Illinois. The successful bid by McCarthy Bros/Clark Bridge JV was for the steel alternative. The bridge design included...
The Tatara Bridge - World's Longest Cable-Stayed Span
The Tatara Bridge now under construction has the main span length of 890m which will be the world's longest in cable-stayed bridges when completed. Except for certain lengths of prestressed...
Research and Development ? Why bother?
As the world becomes a true global marketplace, the ramifications of this change is felt in all aspects of business. Products and services from around the world are beginning to appear...
Cut and Cover Construction of the SSC Injector Tunnels
The injector system of the Superconducting Super Collider (SSC) constitutes the string of tunnels where protons are accelerated to near the speed of light and injected into the main collider...
High Strength Shotcrete and Concrete on the SSC Project
This paper addresses the technical aspects related to the use of high strength shotcrete and concrete on the Superconducting Super Collider (SSC) project. 7,000 psi shotcrete and 8,000...
A Peice-wise Linear Evaluation of Masonry Infills Subjected to Out-of-plane Seiesmic Drift
This paper summarizes the out-of-plane testing and analytical modeling of a full-scale unreinforced masonry (URM) infilled frame and a bare frame without infilling. The testing was part...
Wind Effects and Countermeasures During Erection of a Cable-stayed Bridge
The cable-stayed bridge over the Karnali River in the Kingdom of Nepal was completed in 1992. Extensive wind tunnel testing indicated the likely wind response during construction. Several...
Wind Studies of the Owensboro Bridge, Kentucky
Wind tunnel studies on the Owensboro Bridge are described in this paper, including 1:50 scale sectional model tests and 1:160 scale aeroelastic model tests. Comparisons are presented and...
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...
Biaxial Testing of Brittle Repair Material for Rigid Pavements
