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...
Safety Evaluation and Verification by Field Testing of Concrete Bridges
This paper describes a method of safety evaluation of concrete bridges in service and the verification of the evaluated results by field tests. The field tests to evaluate structural safety...
Current Bridge Research at Iowa State University
For the past 20 years the majority of the structural engineering faculty in the Department of Civil and Construction Engineering at Iowa State University (ISU) have performed research...
Dynamic Characterization of Posttensioned Rods in Stressed Timber Systems
A new approach is presented to monitor the levels of force in posttensioning rods in stressed timber systems. The dynamic response of the rod under an impact load is characterized and...
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 Coastline Between Rio De Janeiro and Cabo Frio
The coastline between Rio de Janeiro and Cabo Frio is characterized by successive long beach arcs, oriented in the East-West direction. The beaches are separated by rocky headlands resulting...
Managing a Megaproject
The tunnel beneath the English Channel is an unusual construction project because of the private sector financing of infrastructure as well as the price, $9 billion, and the international...
Selected Papers from Chinese Journals of Structural Engineering
This book is an initial effort to introduce selected papers from journals published by the China Civil Engineering Society to ASCE membership. The twenty papers in this volume were selected...
Highway Erosion Remedial Measures
Soil erosion from highway ditches, cut slopes and fill slopes present a continuous problem to roadway designers, geotechnical engineers, and construction and maintenance personnel from...
Cincinnati's Dream Team
For years, the cries of Cincinnati's Public Works Department and its civil engineers for infrastructure repair fell on deaf ears. In 1986, Mayor Charles Luken tried a new...
Water Quality Monitoring of Highway Construction
The primary objective of water quality monitoring, as it relates to highway construction, is to obtain quantitative information to ensure that runoff from the construction site does not...
Design, Construction and Testing of Repairs to the Low Level Outlets at Terzaghi Dam
Operation of the low level outlets (LLOs) at Terzaghi Dam in southwestern British Columbia resulted in severe cavitation at operating heads significantly lower than design. Modifications...
Tunneling through an Existing Concrete Masonry Dam
The Gregory B. Jarvis Hydroelectric Project is located in Upper New York State on the West Canada Creek. Existing facilities include a non-overflow concrete gravity dam, 65 feet long and...
Cofferdams: An Integral Part of Small Hydro Design
Cofferdam construction costs can be a major factor in the viability of a small hydro development. For this reason, cost-effective design and construction are critical. A cost-effective...
Flashboard Alternatives Including Rubber Dams
This paper reviews some common flashboard methods used in the northeastern part of the U.S., and discusses the advantages and disadvantages of each type. The inflatable rubber dam is presented...
Hydraulic Features of Canyon Lake Hydropower Plant
The original hydraulic features of the Canyon Lake dam were well adapted to the addition of hydropower. Design, construction and anticipated operational details of the added hydropower...
Newfoundland's First Arch Dam Construction Versus Climate
Paradise River arch dam is located in a narrow box canyon about 50 m deep and less than 10 m wide at streambed. It is a thin arch dam, especially sensitive to temperature loads, thus contraction...
Feasibility, Licensing and Design: Bradley Lake Hydroelectric Project
This paper describes the licensing, environmental, engineering, and design aspects of the project. Due to the project's remote location and geological setting, the paper will...
Siphon Penstock Installations at Hydroelectric Projects: A Survey of Design, Construction and Operating Experience
There can be advantages to using siphon penstocks at small hydro projects, particularly those constructed at existing dams. One problem, however, is a lack of documentation of siphon penstock...
CAD Speeds Viaduct Replacement
Lack of an available detour around construction of a major viaduct spurred city officials in Reno, Nev. to build a bridge nearby to serve the purpose. Although funded separately, the permanent...
