A survey of bridge concepts built in recent years by the State Enterprise Dopravni Stavby, Olomouc that ranks among the largest building trade firms in Czechoslovakia. This firm chooses...
Beautiful Bridges and Highways in the West
This paper recounts 75 years of progress in the design of aesthetic bridges and highways in the west. Not a new idea, there are numerous existing examples showing that the goal of good...
An Optimal Design of Steel Pipe Pile Foundation
This paper presents an optimal design method for the steel pipe pile foundation of bridge pier using a nonlinear programming. It is firstly assumed that an imaginary wall model behaves...
Fatigue Strength of Corroded Rolled Beams
Highway and railway bridges fabricated from ASTM A7, A36, and A572 steels will corrode if the paint system is allowed to fail for lack of maintenance. Corroding members lose cross section...
Fast-Track Concrete Paving
Well known for its corn production, the State of Iowa has been seeding a new product for the past several years. 'Fast Track' concrete has grown along the edge...
LRFD for U. S. Bridge Design ? Validation Issues
During the 1987 meeting of the AASHTO Subcommittee on Bridges and Structures, recommendations from the National Cooperative Highway Research Program (NCHRP), Project 20-7/31, regarding...
Wind Resistant Design Manual for Highway Bridges
The new wind resistant design manual for highway bridges has been required recently in Japan. The working group was organized in the Japan Road Association is 1984 to prepare the manual....
Toward an LRFD-Based AASHTO Bridge Specification
During the 1987 AASHTO Bridge Committee Meeting, recommendations from NCHRP Project 20-7/31 regarding the development of a probability-based LRFD bridge specification were accepted. NCHRP...
Bridge Loading Evaluation for Limit States Design in Japan
Some statistics regarding bridges in Japan are firstly explained. Next, the limit states design which will be introduced in 1995 for highway bridge design specification in Japan is briefly...
Fatigue Life Evaluation of Welded Structural Details in Steel Highway Bridge
Stresses in highway bridge members, fatigue crack propagation behavior and long life fatigue strength properties of welded members under traffic loadings and prediction of fatigue life...
Evaluation of Bridge Safety and Remaining Life
In developed countries, the emphasis on the infrastructure is changing from new construction to the safe maintenance of existing structures. Highway bridges represent an excellent example...
Study and Design of Multi-Span Continuous Bridge
Multi-span continuous bridges which have been constructed in the Metropolitan Expressway Public Corporation are briefly explained. Some studies were carried out into their behavior. The...
Development of Skewed Element for the Concrete Pavements
In the recent years, highway engineers introduced skewed joints in the concrete pavement with a 4 foot to 5 foot skew on a 24 foot width pavement, which results in only one wheel crossing...
The Effect of Stiffness Degradation on the Three-Dimensional Seismic Response of Highway Bridges
This paper describes the effect of modeling of the inelastic pier behavior on the seismic response of three reinforced concrete bridges. Each bridge was analyzed twice once using a yield...
Vertical Response Data from the Dominion Road Bridge Test
In January and February of 1985, two bridges were tested in New Zealand using simulated earthquake loads. The objective was to determine the in-situ seismic response of two reinforced...
Effects of Vertical Motion on the Inelastic Behavior of Highway Bridges
The response of typical highway bridges to the vertical component of earthquake ground motion has a significant effect on their elastic behavior. When vertical motions are considered along...
Structural Foundation Practices for Highway Projects
The state-of-practice by State transportation agencies, in the area of structural foundations, is compared between the late 1970's and the present. The structural foundation...
The CADD Landfill
Designing landfills with CADD, engineers have reduced cut and fill calculations from two weeks to two days. Aerial surveys arrive on magnetic tapes and are loaded into computers by in-house...
Automating Design of Boston's Artery
Boston's Central Artery project is being designed with in-house programs that are helping to overcome problems caused by the sheer volume of diversified data being handled...
Constraint Based Design from Research into the Classroom
Design is constraint oriented; much of the design process involves the recognition, formulation and satisfaction of constraints. Constraints are continually being added, deleted and modified...
