Data Acquisition and Process Control
Automatic data acquisition and control systems are discussed. Computerized systems are used in laboratory, field, and industrial applications to acquire, process, and control test parameters....

Computers in Civil Engineering Practice
The current use of computers in civil engineering is discussed. Engineers' expectations from computer use are outlined and realistic considerations are presented. Advantages...

Pavement Roughness and Rideability: A State-of-the-Art Review
This paper reports on the results of a review of the literature and ongoing research concerned with pavement roughness and rideabiity. The material covers definitions and concepts, subjective...

Wave Force Coefficients for Vertical Cylinders
Wave forces on small sections of vertical tubes were measured in a wave tank test. The tube sizes and the wave parameters were such that both the inertia and the drag dominated areas were...

Ice Engineering Design of Marine Piling and Piers
Design criteria and structure designs for pilings, piers, and docks subject to ice are presented. Included are estimates of stationary and moving horizontal and vertical ice forces, types...

Wind Tunnel Modeling of Building Internal Pressure
An inspectional analysis is made on the differential equations governing the fluctuations of the building internal pressure generated by wind for both single and multi-room buildings....

Underground Transit Station Construction in Japan
Technologies used in Japan for constructing underground stations for heavy-rail urban rapid transit systems are described. Two example projects have been chosen that illustrate different...

Scheduling: Effective Methods and Techniques
Network planning and analysis (CPM) is a proven means to outline the many activities to be performed and to investigate the feasibility of a given construction project. Commencing with...

Contract Administration: A Resident Engineer's View
Professional liability related to field work is a major concern of the consulting profession. Field personnel should review the plans and specification in the pre-construction period and...

Modernized Metric System—SI—The American Choice
Americans have played a major role in the development of the new International System of Measurement Units (SI). The world is moving rapidly in the adoption of this modernized metric system....

Planning, Scheduling, and Communicating on Crew Productivity
Construction project planning and scheduling along with communication of the plan have major impact on the productivity of field crews. Though the size of the impact is practically impossible...

Generalized Wave Equation in Finite Domains
A generalized equation governing one dimensional wave propagation in finite domains is solved by employing the finite Sturm-Liouville transform. The formulation includes the effects of...

Technical Aspects of Metric Construction
The Water and Power Resources Service, formerly the Bureau of Reclamation, has begun construction of a number of major projects using SI metric units. Technical aspects of the design and...

The Earthquake Problem in the Eastern United States
Earthquakes in the eastern United States have longer recurrence times, less attenuation of damaging ground motion, and occur in more diffuse source zones than their western counterparts....

Municipal and Industrial Water Demands of Western U.S.
Municipal water requirements are directly related to population whereas industrial demands are related to the level and type of industrial activity. The emphasis on domestic energy production...

U. S. Grain Exports: Transportation and Pricing Systems
Exports of grains from the U.S. in 1979 were 4.6 billion bushels (121.1 million tonnes) and are projected at 6 billion bushels (157.9 million tonnes) by 1985. Over half of these will flow...

Thermal Plume Area Calculation
A simple formula for the surface area of a thermal plume is proposed, appropriate for application to a depth-limited surface discharge. The formula is based upon thermodynamic and kinematic...

Three-Parameter Failure Criterion for Concrete
A general, three-dimensional failure criterion for plain concrete and mortar is proposed. This criterion is formulated in terms of the first and the third stress invariants of the stress...

The Ethics of Serving Two Masters: An Engineer's Dilemma
The question posed is Does the engineer serve two masters——the employer and the public welfare? Through analogies of the decision making process to common everday problems and a look at...

Control of Tall Building Under Earthquake Excitation
A method of analysis for tall buildings implemented by active control systems and excited by earthquake ground motions is proposed. The effectiveness of the active mass damper and the...
