Do Civil Engineers Have an Ethical Responsibility to their Client at the Expense of the Environment?
The application of engineering ethics to the environment is at the center of the debate regarding sustainable development. If the environment is to be held above client needs, say many,...
When the Levee Breaks
As repairs to the billions of dollars in damages left by the Mississippi and Missouri floods continue, many engineers believe it is time to step back and see if there are better ways of...
Checking Concrete Growth
When the Tennessee Valley Authority built its dams in the 1930s, instrumentation installed in the massive concrete detected a defect that would later cause major problems: concrete growth...
Real-Time Control for a Robotic Rebar Bender
Job conditions and variability in the properties of the stock material combine in a rebar bending operation to create a challenging environment for a robotic bender. This paper reports...
Analysis of Inflating Habitable Space Structures with neomass (near-Earth-object mass)
The discovery of near Earth objects (NEOs), during August 1992, and that one of them is a dormant comet, dramatically changed the potential availability of near-Earth resources. NEOs provide...
Biosphere II - Its Effects on Space Colonization
In the middle of the Arizona desert, a strange sight can be seen. A small world with ecosystems and different climate zones, just like Earth, is enclosed in glass and steel. The 3.15 acre...
The History and Present Status of Microwave Aircraft
The history of microwave-powered aircraft is reviewed from the point of view of interaction between the technology of beamed microwave power transmission and the applications for it. the...

A Dome For the 21st Century
Putting a circular dome on a square building--the classical architectural design challenge--takes on new proportions at the Federal Building and Courthouse in Charleston, W. Va. The 170...
Debating Steel - Connection Design
The debate about responsibility for structural-steel-connection design is among the hottest engineering disputes of our generation. Meetings have been held on the subject, articles written...
High-Strength Concrete Columns in High-Rise Buildings
Strength and ductility of high-strength concrete columns were investigated by examining available test data. The results are summarized in terms of load and ductility capacities of columns....
Cumulative Impact of Heavy Permit-Trucks on Steel Bridges
In many parts of North America, special permits are issued to heavy vehicles without considering their cumulative effect on steel bridge components. Such overloads may initiate crack propagation...
U.S. / Japan Large Scale Cooperative Research Program for Steel Structures
The US/Japan Cooperative Research Program Utilizing Large Scale Test Facilities for Earthquake Resistant Design was initiated in 1980 using a combination of full-scale, small-scale, subassemblage...
Corrosion Resistant Epoxy-Coated Reinforcing Steel
Research conducted in the 1970s to evaluate and develop criteria for nonmetallic coatings to protect steel reinforcing bars embedded in concrete bridge decks from the corrosive action...
First Bank Place: A Composite Cruciform Spine
The First Bank Place, designed by the internationally known architectural firm of Pei Cobb Freed and Partners, is a granite-clad, 56 stories tall building in downtown Minneapolis. Presented...
Composite Walls as Shear Elements in Tall Structures
This paper describes a system of composite walling that can be used as a lateral load resisting system in tall structures. The composite walling comprises two skins of profiled steel sheeting...
