Prediction of Deformations Due to Heat Curving
This paper summarizes the state of the art in the thermal deformation techniques. Alternate analytical methods are described. The limitations and accuracy of these models are noted, and...
The GEV Distribution in Drought Frequency Analysis
Three decades have passed since A. F. Jenkinson found the general solution to the Stability Postulate, which is the condition that all the extremes must meet, and after him that solution...
Probabilistic Models of Fatigue Crack Growth
The reliability of a structure against metal fatigue is a problem that has been of concern to engineers for a very long time. This problem was one of the first to be approached probabilistically,...
Moment Rotation Curves for Double Framing Angles
Moment-rotation curves for bolted framed steel connections are derived from force-deflection data obtained from laboratory tension and compression tests of angle segments. These derived...
Fracture-Mechanics-Based Fatigue Life Estimate
Fatigue lives of tee-shaped weldments are estimated using fracture mechanics concepts and crack growth rate data. Fracture mechanics is used to develop an approximate expression for stress...
Axial Fatigue Model for Wire Rope Strand
A numerical fatigue model for cables and rope strand subjected to fluctuating axial tension has been developed. This model determines the maximum wire nominal and Hertz contact stresses,...
High Strength Concrete - A New Material
In this paper, the material properties and structural member behavior of normal and high-strength concretes are summarized. The current ACI code recommendations are based on results of...
Structural Considerations of Cellular Concrete
Although not normally considered to be a structural material, cellular concrete possesses characteristics which may result in its having structural applications in building and structural...
Mechanical Properties of Model Ice Rubble
Experiments were conducted to measure the mechanical properties of bulk ice rubble. Tests were performed under isothermal and plane strain conditions. Fresh water ice blocks were used...
Case Studies of Displacement-Induced Fatigue
The potential for displacement-induced cracking is a result of the co-existence of two conditions: an abrupt change in stiffness and a periodic force opposing it. Case studies of retrofitted...
Materials and Member Behavior
Each of the papers in this book covers some aspect of material properties. New developments in cold formed steel are reviewed. The strength, stiffness, and ductility of steel connections...
Studies With, and Testing of the McCormick Pneumatic Wave Energy Turbine With Some Comments on PWECS Systems
Work done in developing concepts for pneumatic wave energy conversion based on theoretical analyses of the hydrodynamic, pneumatic, and mechanical systems with some estimates of performance...

Engineering Mechanics
6th Conference
Abstract only. A collection of abstracts of papers presented at the Sixth Engineering Mechanics Specialty Conference, held in Buffalo, New York, May 20-22, 1987....
Economical Computer Controls for Low Head Hydro
Small power systems based on renewable energy sources such as low head water falls, wind, solar and ocean tides all suffer from stochastic changes in input power. Economically viable,...
Small Scale and Low Head Hydro Development in Canada: An Overview of Federal Activities and Policy
Through research and development, new small turbines have been tested and a Darrieus type vertical axis hydraulic turbine (VAHT) has been developed and field tested. Manuals for hydrologic...
Small Hydropower Potential in Missouri
The hydropower potential of small head plants on the Gasconade River was investigated. Since, it is felt that small head plants will have less environmental impact, thus it will be more...
Selection of Small Hydro Project Sites
In the course of studying nearly forty areas in Peru to identify possible sites for small hydro development and in order to select the best in each area for detailed design, the Authors...
Criteria for Selecting Turbine-Pumps Used in Mini-Hydro Power Units
The present paper is aimed at studying turbine-pump units operating at low heads. The proposed methodology is based on the global matching of the turbine and the pump so that both will...
A Marine Thruster in Small Scale Hydropower
A 70 kW hydroelectric plant utilizing a marine thruster as a turbine was commissioned in May, 1985. The thruster, the construction management, the site conditions and the testing program...
