Small Kaplan Versus Tubular and Francis Turbines
Mossefossen Power Plant is situated in the centre of the small town Moss in the southern part of Norway. Water flows from an existing dam through a 9 m**2, 175m long tunnel to the powerhouse...
Design Criteria for Generators in Low-Head Hydro-Power Plants
Principal characteristics and design features of such generators are discussed and options and preferences in their selection mentioned. Effects on inertia constant, efficiency, reactive...
Index Testing?Relative Turbine Performance
The Index method of testing hydraulic turbines consists of making a test in which the value of power output and head are measured and in which the quantities of water and velocity head...
Control System Design Considerations for Small Hydro Projects
This paper deals with the philosophy that must be embraced when specifying a fast track small hydro project. The major areas discussed are: the role of control systems in the context of...
Galt Energy's Inverted Siphon System
Galt Energy Systems' involvement with attempting to standardize the civil component began with studies at small remote sites in Northern Ontario. The system design evolved...
Finite Element Discretization for Mixed-Mode Fracture Problems
The finite element discretization of mixed-mode problems in fracture mechanics is investigated. The characteristics of the mesh near the crack affect the accuracy of the finite element...
Tunnel Closure Prediction by Finite Element Method
Discussed is the tunnel closure prediction of a drainage tunnel using finite element methods. Separately, three finite element programs were used to predict the closure. The results of...
Improved Method for the Dynamic Response of Bilinear Systems
A procedure is presented to eliminate the error introduced in the step-by-step numerical integration of the equations of motion of hysteretic bilinear systems subjected to earthquake excitations...
Interactive CAL Modules for Mechanics of Solids
Traditionally the basic engineering course in 'Mechanics of Solids' has proven to be a challenge to both the students and faculty, for although the fundamental...
Practical Modeling of Bar Slippage in R/C Joints
A procedure based on the displacement method of analysis has been developed for analyzing the behavior of beam reinforcement crossing the interior beam-column connections under seismic...
Mechanics of Crack Propagation in Stiff Clays
Many stiff clays forming part of natural slopes and earth dams exist in the fissured state. When these cracks are subjected to gravity induced normal and shear stresses they may propagate....
Lateral Pressure in a Stiff Clay
A series of consolidated undrained and drained triaxial tests and oedometer tests were performed on horizontal and vertical specimens taken from an overconsolidated cretaceous clay. An...
Qualitative Physics and the Prediction of Structural Behavior
A key need in the application of expert systems to structural engineering design is the ability to predict structural deformation and stresses in the absence of a quantitative model. The...
Seismic Tests of Friction Damped Steel Frames
This paper presents the results obtained from qualification tests of a new friction damping system, which has been proposed in order to improve the response of Moment Resisting Frames...
Strengthening of a Multi-Story Building with Deflection Constraints
Occasionally the existing structural or nonstructural systems of a building being strengthened require the imposition of deflection constraints or limits in order to avoid an undesirable...
Modal Analysis of Random Vibration with Hysteresis
A model for the zero or non-zero mean random vibration response of hysteretic plane frames is summarized, in which the plane frame is idealized as a series of elastic sub-elements connected...
Dynamic Response Moments of Random Parametered Structures with Random Excitation
First and second order statistical response moments are formulated for linear multi-degree of freedom dynamical systems having both random load and random structural characteristics. A...
Stochastic Response of Structures with Appendages Containing Fluids
Following a perturbation technique a procedure is developed to compute the modal properties of a system consisting of a fluid containing appendage attached to a multi-degree-of-freedom...
Mobile Cranes on Barges?A Naval Architect's Perspective
The purpose of this paper is to present a procedure for analyzing the effect of heel on a barge/crane combination in order to determine its suitability for lifting a load of given size...
A Modern Cone Penetration Testing Vehicle
The geotechnical group at the University of Florida recently purchased a new insitu testing cone truck. This is a powerful, all wheel drive, off-the-road vehicle designed specially for...
