Sedimentation Impacts on a Pumpback Storage Facility
Concern over future sedimentation impacts at a proposed pump storage hydroelectric facility at Lake Francis Case on the Missouri River led to use of a numerical model to analyze lake hydrodynamics....

Automatic Calibration of Conceptual Rainfall-Runoff Models
An automatic calibration strategy applied to land and channel components of the National Weather Service River Forecast System is outlined. Aspects discussed include the objective function...

A Comparative Study of Different Base Isolators
A comparative study of the effectiveness of four different base isolators is carried out. The structure is modeled as a rigid mass and the accelerograms of the North-South component of...

Response of Structures to Horizontal-Vertical Earthquakes
In the present work, the responses of a class of hysteretically nonlinear structures subjected to the combined horizontal and vertical random ground accelerations are studied. A massless...

Application of Normal Integration Formulas to Bridge Reliability Analysis
Structural reliability analysis often involves extensive integration of complex multivariable functions. Special techniques can be used to reduce this numerical effort. This paper deals...

Seismic Response Component in the Risk Assessment of Dams
The risk analysis model for dams that is discussed in this paper considers the probability of an initiating event and the following conditional probabilities of the system response, the...

Time-Domain Dam-Reservoir-Interaction Analysis Based on Boundary Elements
For a reservoir with an arbitrary shape of the upstream face and of the bottom including an adjacent regular part of constant depth extending to infinity, the hydrodynamic-stiffness matrix...

Simulation Algorithms for Offshore Structures
A rational procedure for characterization of water depths for a random sea state is developed, in context with linearized wave theory. The importance of using the expressions for 'intermediate...

Time Domain Structural Parameters Identification
Identification techniques for linear lumped-parameters models of vibrating structures are critically assessed using data produced by numerical simulations. The structural model is excited...

Buckling of Thin-Walled Members by p-Version of FEM
P-Version of the finite element method (FEM) is used for one-D and three-D modeling of thin-walled open sections and axial compressive load. Equal angle and channel sections are used for...

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,...

Tall Building Stability -- Practical Considerations
Simple techniques for including lateral stability effects in the design of tall buildings are proposed. The application of these techniques in the design of a 66-story building is described....

Teacher Friendly Transportation Programs
This contribution describes a set of computer programs that has mainly been developed to demonstrate operating and possibilities of mainframe programs during lectures. The program set...

Running Rucus II on a Microcomputer
Since the preliminary version of the RUCUS II (Run Cutting and Scheduling System) was released by UMTA in 1982, the system has achieved considerable acceptance by transit properties. These...

Hydraulic Engineering
The papers in this book were presented at the ASCE National Conference on Hydraulic Engineering, August, 1987, Williamsburg, Va. The objective of this conference was to provide a forum...

Operational Experiences With a Wells Turbine on a Wave Powered Navigation Study
The objective of the research programme was to design a 100W Wells turbine generator unit which could be matched to standard tail tube buoys. Optimization of the power conversion chain...

Evaluation of Sediment Transport and Friction Factor Equations Using MOBED
Three sediment transport rate equations and the same number of friction factor equations for mobile boundary channel flows were evaluated using a mobile boundary flow model called MOBED....

Twisting in the Wind
Wind tunnel tests are being used increasingly to test the aerodynamic stability of bridges. Many designers think these tests should be used early in the conceptual design stage, rather...

An Improved Method to Predict Annual Transit Fare Revenues from Mid-Year Results
Effective short-term financial management of transit systems requires the same three general actions necessary to manage all service oriented industries: 1)monitoring of short term (usually...

A Stochastic-Conceptual Reservoir Inflow Forecasting Model
The development of a method to improve real-time forecasting of reservoir inflows for the purpose of minimizing water loss through spillage is presented. Streamflow forecasts are computed...
