Building Trends: The View from Houston
Highligts of the major changes in building design and construction over the past decade are presented from a structural engineer's viewpoint. The areas covered include: (1)...
West Coast High-Rise Condo Opts for Ductile Concrete Frame
In the past, the vast majority of high-rise buildings constructed in earthquake prone areas of the West Coast have employed a steel frame. However, recent advances have made it feasible...
Throgs Neck Bridge: Why Did Its Deck Deteriorate?
Rapid deterioration of the concrete roadway decks of the Throgs Neck Bridge approach viaducts was found to be due to secondary tensile and fatigue stresses brought on by deflection of...
Word Processing: Office Personnel's Friend or Foe?
The introduction of word processing centers into the workplace brought about the restructuring of office duties and new demands on workers. Word processing received blame for a variety...
Underpinning with Chemical Grout
During construction of Pittsburgh's new subway, it became necessary to protect the foundations of six downtown buildings. A detailed study of building foundation support options...
Public Works and Unemployment: A Panel Discussion
In March 1983,
Proposition 13: Impact on California Public Works
The effect of proposition 13, which was passed in California in June 1978, has hurt the ability of local governments in the state to raise funds to construct new infrastructure and maintain...
Highway Projects -- Can They Be Done in Half the Time?
Delays in highway construction projects result from time-consuming federal and state review procedures, public opposition and funding restrictions. The majority of delays in highway projects...
Frontiers in Hydraulic Engineering
These proceedings include approximately 140 papers presented in the ASCE Hydraulics Division Specialty Conference, August 1983, Cambridge, Mass. The principal aim of the conference was...
Design of Offshore Pipelines for Ice Environments
Design and installation of offshore pipelines in cold regions requires special care. Low ambient temperatures may cause increased friction losses in oil and gas lines due to wax crystallization...
Design of Ships for Ice Environments
A number of feasibility studies have proven the reliability of marine transportation for the Arctic. Current research and development in this field, especially in the USA and Canada, is...
River and Lake Ice Processes Relevant to Ice Loads
Ice effects on engineering structures in inland waters are more widespread than generally appreciated. Troublesome ice conditions can be expected regularly north of the 0 degree C January...
Measurement of Ice Forces on Structures
Methodologies and techniques are discussed for measuring ice forces on fixed structures situated in rivers and lakes. The usual method of measuring ice forces is to place a load frame...
Design of Bridges for Ice Forces
Sources of knowledge on ice forces and ice effects on bridges are listed and discussed briefly. Comments are made on experience of damage by ice and on the influence on bridge costs of...
Design of Navigational Structures for Ice Forces
An overview of ice conditions and the types of ice action that are hazardous to navigational structures is presented. Depending on the circumstances, ice failure against structures occurs...
Design of Submerged and Floating Structures
The objective of this paper is to present an overview of the state-of-the-art of ice engineering as applied to submerged and floating structures. Five specific design studies are reviewed,...
Advisory Notes on Lifeline Earthquake Engineering
A Report
A state-of-the-art review of seismic design of lifeline facilities is presented including some insight as to how lifeline facilities have performed in past earthquakes. Information is...
In Search of Ancient Engineers
Many examples of pre-Columbian civil works have been uncovered in North and South America. Some reflect well-organized technologies comparable to those of the Old World of the same time...
Structural Steel Details: Is Responsibility a Problem?
Because structural engineers are leaving design of structural steel connections to fabricators, the problem of responsibility for those details has arisen. This article explores a variety...
In Third World Villages, a Simple Handpump Saves Lives
Millions die each year and many more suffer in the developing countries from diseases spread by contaminated water. In fact, it is estimated that 80% of all disease in the world is due...
