Geotechnical Considerations in the Design of the Wando Terminal Wharf Extension, Charleston, South Carolina
The South Carolina State Ports Authority (SPA) is currently examining construction concepts for the proposed 1,200-foot wharf extension and 40 acres of adjacent upland development at the...
Port of Kismayo (Somalia) Rehabilitation
Extensive deterioration of the 2070 ft long four-berth, marginal wharf at the Port of Kismayo necessitated a major rehabilitation to maintain operations. The selected scheme was a steel...
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...
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...
Cable Stays Catch On
The three completed cable stayed bridges in the U.S.�Pasco-Kennewick in Washington, Luling-Destrehan in Louisiana and East Huntington in West Virginia�will soon be joined by another half...
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...
Postmodern Engineering
Momentum Place is a postmodern skyscraper in Dallas designed by architects John Burgee and Philip Johnson. The Datum-Moore Partnership, structural engineers, designed the structural system...
Recyclying of Dust from Electric Arc Funances�An Experimental Evaluation
Each year the electric arc steelmaking industry generates approximately 650,000 tons of dusts containing valuable metallic resources such as iron, zinc, lead, and chromium. EAF dust is...
Risk-Based Design of Inspection Programs for Detecting Leaky Underground Storage Tanks
A mathematical framework is developed for estimating the effectiveness of large-scale inspection programs for leaky underground storage tanks. The framework incorporates the leak likelihood...
Rehabbing under Traffic
Redecking the Golden Gate Bridge with a light weight orthotropic steel plate deck left the 49 year old monument 11,000 tons lighter, 2 feet wider, and ready to carry traffic for the next...
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,...
Top Projects of 1986
In the 1986 ASCE competition to select the Outstanding Civil Engineering Achievement of the Year, 14 projects were nominated. This article describes the 10 non-winners. Technically the...
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...
Record High Rise, Record Low Steel
The Bank of China, under construction in Hong Kong, will be the world's fifth tallest building. In spite of the extraordinary codes for that city�high winds, and high live...
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...
Seismic Design of Braced Steel Frames
Seismic behavior of a six-story, K-braced structure without backup ductile moment-resisting frames designed according to the current Uniform Building Code is studied in this paper. The...
