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 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...*
