Seismic Research Program for Highway Construction
This paper provides an overview of the highway research program being conducted by the National Center for Earthquake Engineering Research (NCEER). This six-year program, which is sponsored...
Seismic Study of Historic Bridges in Eastern United States
The main objective of this paper is to study the Barrackville bridge and its response in resisting static and seismic loads. Since the design was based on controlled deflections, the analyses...
Continuity in Precast Prestressed Concrete Girder Bridges
An experimental study conducted to evaluate the behavior of pretensioned bridge members made continuous with a cast-in-place concrete slab and diaphragm is summarized. In this study, the...
A Study of Jointless Bridge Behavior
The pressing need for maintenance free and low construction cost bridges, has increased the interest and activity in building integral or jointless bridges. The investigation of the behavior...
Design of Box Girder Bridges by Nonlinear Theory
A modified design procedure applicable to a large number of conventional box girder bridges with longitudinally-stiffened flanges has been presented in this paper. It determines the ultimate...
Harmonization of Reliability-Based Timber Engineering Codes and Standards
An overview of activities related to harmonization of reliability-based timber design codes and standards is presented. The overview is based on information generated through a NATO Advanced...
Use of Composite Timber-concrete Floors in Residential Buildings
Timber-concrete floors are widely used in the Gulf region for its resistance to hot and aggressive environment of the area. However, due to the fact that no shear connector is provided,...
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...
Evaluation of Wood Floor Vibration Design Criteria
In the United States, floors in wood buildings are designed according to strength and deflection criteria under static uniform loads. With the introduction of engineered joist products...
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...
Load and Resistance Factors for Bridge Design Code
The paper summarizes the code development procedures used for the new LRFD (load and resistance factor design) bridge code. The current specifications use allowable stresses and/or load...
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...
Unified Code Provisions for Concrete Bridges
Provisions on limiting the flexural reinforcement adopted in the new AASHTO LRFD Specification for Bridge Design are summarized (1). They address minimum and maximum levels of reinforcement...
Design Guidelines for the Use of Debonded Strands
In this paper, presented are the flexural tests performed on beams containing debonded strands. Results show that debonded strands can be used reliably and safely, stipulating that the...
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....
The Normandie Bridge
The Normandie Bridge will have one of the longest cable-stayed spans in the world, i.e. 856 m long. This paper briefly describes the design of the bridge, with the concrete access spans...
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...
A Self-Balancing Laminate
A self balancing wood laminate has been developed based on the principle of orthotropic elasticity. Lumber is cut into three sections in the flatwise plane and each side member is turned...
