Development of Prestressed Concrete Fender Piles
An ongoing effort is reported to develop prestressed concrete fender piles for use in a wide range of pier fendering applications. Preliminary analysis and testing results indicate that...
Puget Sound Alluvium: A Challenge in Design of Pile Supported Port Facilities with Dredged Slopes
The geotechnical investigation, evaluations, and recommendations for the Port of Seattle Terminal 18/20 Improvement Project are described and compared with observed performance during...
Construction Materials for Civil Engineering Projects
The materials of construction in use today have grown in number, increased in complexity, expanded in application and multiplied in utilization over those in use just a short time ago....
Salvaging the Zilwaukee
In 1982, construction of the Zilwaukee Bridge in Michigan was disrupted when the launching truss failed to hold a precast concrete segment near Pier 11N, severely deflecting the cantilever...
The Mile High Dream
For the 1986 Tall Buildings Conference in Chicago, a group of experts studied the implications of a mile high skyscraper to be built of concrete. It is 500 ft square at the base, designed...
Asphalt Pavement Modifiers
Modifiers or additives to asphalt concrete pavements are being researched or marketed by many major chemical firms. Modifiers or additives are used to stiffen the asphalt in hot weather...
CAD Goes into Analysis
In the past, computer analysis of a design was always a separate and distinct step from CAD. Now, an increasing number of systems are combining the two. One system, SSCAD, allows the engineer...
Expert Systems Enter the Marketplace
Civil engineering expert systems (computer programs that incorporate some of the decision-making capabilities of the top experts in a given subdiscipline) are beginning to come on the...
Tunnel Ceiling Replaced over traffic
The ceiling of the Holland Tunnel under the Hudson River, connecting New Jersey and Manhattan, was 59 years old and needed replacement, a big job because there are 3 miles of ceiling in...
Sulfide Corrosion and Control in the City of Modesto Primary Effluent Outfall (
The City of Modesto has a 60 inch diameter, 6- one-half mile long reinforced concrete pipeline conveying primary effluent from the primary treatment plant to the remote oxidation pond...
Long Reinforced Concrete Columns
Papers selected by the Reinforced Concrete Research Council of ASCE. This collection contains 13 papers reporting the results of a series of studies,...
Construction of Roller-Compacted Concrete Pavement
Roller-compacted concrete pavement (RCCP) is the product of a relatively new concrete paving technology in which a zero-slump portland cement concrete mixture is spread with modified asphalt...
Equipment Requirements for Concrete Recycling
Concrete recycling projects have been completed in a number of states. As the transportation infrastructure ages, concrete recycling will become a common construction operation. Concrete...
Restoration of Navy LTA (Lighter Than Air) Hangars
In 1942 and 1943 the Government constructed a series of 16 blimp hangars at ten Naval Air Stations along the east coast, west coast and gulf coast. The hangars erected in pairs housed...
Case Studies in Upgrading of Wood Trusses and a Heavy Timber Building
Three case studies in upgrading and rehabilitation of wood structures are presented. One case study relates to three 30m (100ft) span bowstring trusses that had to be cut at various span...
Evaluation of the Seismic Performance of Buildings
The aim of the paper is to present the different existing methodologies available for the assessment of seismic damage to buildings. The approach aims towards the development of a mini-computer...
Supply Side Engineering
In New Jersey, the Hackensack Water Co., a private utility, and the North Jersey District Water Supply Commission, a state agency, are jointly completing Wanaque South, a $151 million...
Seismic Response of Pipes Supported on Complex Frames
Analytical approaches and modeling techniques used to calculate seismic responses of piping systems, supported on complex open-frame structures, are evaluated. Seismic responses are obtained...
Probabilistic Limit States Design of Moment-Resistant Frames Under Seismic Loading
This paper focuses on the development of a methodology for the optimal probabilistic limit states design of seismic-resistant steel frames. A mechanism for allowing the designer to include...
Connection Panel Zone Deformation in Steel Frames
Conventional analyses of frameworks are usually carried out without considering the effect of panel zone deformation on frame behavior. As a result, center-to-center distances rather than...
