Reliability-Based LRFD for Transmission Structures
A simple reliability-based Load and Resistance Factor Design (LRFD) method is proposed for the structural design of electric transmission lines. With the proposed method, the designer...
Plastic Design Requirements of the AISC Proposed LRFD Specification
The American Institute of Steel Construction proposed LRFD Specification (1) has recently completed a one year period of trial use and review. This paper discusses the background of the...
Probing the Past
In Denver, Colorado, 12 buildings of an old abandoned brewery complex were to be renovated into a 270,000 sq ft shopping, entertainment and restaurant complex. Rather than conduct a thorough...
Testing for Salt Damage
Salts used to melt snow can contribute to deterioration of concrete structures. Various tests were used to determine the extent of damage in two structures in Rochester, N.Y. One is an...
In-Plane Composite Drains
Drainage of water from outside basement walls, behind retaining walls, or highway cut or fill slopes, has long been a problem. A common solution is the aggregate drain. Often, installation...

Evaluating Data Collectors as a Surveying Tool
Data collectors play an increasingly important role in surveying. The data collector serves as an interface between the total station and the computer and as an electronic assistant to...
River Meandering
The erosion and sedimentation processes associated with river meandering have a profound effect on man's use of rivers and their valleys, as well as the natural environment....
Environmental Engineering
The purpose of the Annual Conference on Environmental Engineering is to pursue scientific knowledge and promote sound engineering judgement and practice in the solution of the many environmental...
Engineering Mechanics in Civil Engineering
The principles of engineering mechanics and the application of these principles to civil engineering problems cover a broad spectrum of topics ranging from theory to practice. These proceedings...
Engineering?The Initial Years
Many young engineers will choose lifelong rewarding careers in engineering. Others will choose to move into fulfilling management careers. Still others will become victims of 'career...
Specialization Vs. Diversification ? Relevant Considerations
The health, well-being, and growth of consulting engineering firms demand a successful strategy covering specialization vs. diversification. A discussion of the pros and cons and some...
Is Your Firm Prepared to Do Infrastructure Work?
Using proper marketing analysis and techniques, multidisciplined firms can capitalize on a number of new business opportunities created by the country's current infrastructure...
Competitive Strategies for Growth
A discussion is given on the approach of Camp Dresser & McKee Inc. to the question of specialization versus diversification in a consulting engineering firm. It was easy to opt...
Specialization or Diversification: The Role of Strategic Planning
The question faced by many consultants and constructors as they plan for the future is: Should we specialize or diversify in order to survive, grow and prosper? This paper proposes that...
Finite-Strain Axial Analysis of Piles in Clay
In the late 1970's, a series of research projects developed simple effective-stress methods to predict the axial capacity of piles in normally-consolidated clay. The method...
Shaft Capacity of Driven Pipe Piles in Clay
A compilation of axial load test records for driven pipe piles in clay published by the American Petroleum Institute is analysed to yield new criteria for skin friction and pile scale...
Cyclic Degradation of Pile Performance in Calcareous Soils
Laboratory data on the skin friction of jacked or driven model piles is presented. Significant cyclic degradation of skin friction commences when the cyclic displacement amplitude reaches...
Residual Stresses in Piles and the Wave Equation
A data base of 18 vertical load tests on driven piles in sand is presented. On average the residual point load was 56% of the measured point load and the residual friction load 19% of...
Vertical Behavior of Two 16-Year Old Drilled Shafts
Vertical load tests were performed on drilled shafts subject to lateral confining and heaving pressures from expansive soil over 16 years. Results indicated mobilized skin friction equal...
