Diffusion Models of Fatigue Crack Growth with Sequence Effects Due to Stationary Random Loads
A new fatigue crack growth model that includes load sequence effects is formulated. This model includes a load history dependent parameter, the reset stress, which reflects the state of...
Probabilistic Analysis of Structures Composed of Path Dependent Materials
A procedure is outlined for calculating the time-evolving CDF's (cumulative probability distribution functions) of structural response variables for cases in which the structure's...
Evaluation Plus History Equals Sewer Renovation
Sewers built in the 1920's were overflowing in the Fort Worth Zoo after moderate rain events. Data from A Sanitary Sewer Evaluation Survey (SSES), plus the Maintenance History...
The Dallas Floodway?Past and Present Successes in Flood Protection Benefits
This paper explores the history of the Dallas Floodway, past performance of the project under various flood conditions and, most recently, the present successes in flood protection provided...
Bond Performance of Reinforcing Bars Embedded in Fiber Reinforced Concrete and Subjected to Monotonic and Cyclic Loads
The primary variables investigated were fiber content and loading history. The reinforcing bar size was ASTM #5. Steel fibers with hooked ends were used with four fiber contents, namely;...
The Benefits of Benefits
The article describes the effects of high turnover on a firm's performance and the potential for helping control it through the benefits offered employees. Historically, benefits...
American Experiments with Laminated and Multiple-Membered Arches
This chapter explores the history of laminated and multiple-membered arches in America....
Influence of Geologic Development on Horizontal Stress in Soil
Geologic history commonly controls the stress in natural soils, so that an understanding of the geology allows an assessment of the horizontal stress. This paper describes mechanistically...
Rock Excavation with Boom Mounted Hydraulic Impact Hammers
A hydraulic demolition hammer mounted on a common backhoe or excavator carrier has gained world wide acceptance in the construction industry as a viable alternative to blasting. This paper...
A Tale of Two Subjects: Modern Physics and River Mechanics
The Einsteins, father and son, made some of the greatest contributions to physics and to river mechanics, respectively. The modern phases of these two subjects are of roughly equal age....
Design of Isolated Small Hydro Stations
This paper presents some ideas concerning the criteria for the design of small hydro power stations operating isolated, and specially those to be installed in remote areas. Subjects covered...
The Renovation of the Mechanicville Hydroelectric Station
The Mechanicville Hydroelectric Facility, owned and operated by Niagara Mohawk Power Corporation, was first developed in 1897. This paper traces its history, relicensing and new design....
Who Pays for the Unexpected in Construction? History, Guidelines and Philosophy for a Successful Resolution
The current procedures for resolutions of construction industry disputes are primarily through an adversarial approach that is costly and time-consuming. If there is to be a 'better...

Geosynthetics for Soil Improvement: A General Report and Keynote Address
The paper summarizes major developments in the field of geosynthetics since the previous symposium in 1980. The paper addresses the engineering functions of major types of geosynthetics,...
Statistical Analysis of Occupant Dynamic Loads
Human-induced load-time histories were modeled by several dependent descriptive parameters. These parameters were treated as functions of two independent variables in a multivariate regression...
The Life and Science of R. A. Bagnold
The purpose of this paper is to highlight and honor the exciting life and many significant contributions made by Brigadier Ralph A. Bagnold to our understanding of hydraulics and sediment...
Interdisciplinary Course in Engineering Education
Few would disagree that an undergraduate education should equip the engineer with more than technical competence. The subject of this paper includes discussion of a senior-level interdisciplinary...
