Dynamic Analysis of Unstable Structural Systems With Prescribed Velocities
Structural systems that have large inextentional deformation, or in other words, deformation without stain are called 'Unstable Structural Systems.' They include cable structures, membrane...

Dynamic Characteristics of Translational Lattice Domes
The feasibility of using lattice domes of various shapes generated by translating a variety of parametric polygons is illustrated and the dynamic characteristics of these lattices determined....

Discrete Field Stability Analysis of X-Braced Lattices
The three-dimensional X-braced lattice is used as a compression member in structures ranging from the long span roof of buildings to radio and television antennas. In such cases the design...

Ultimate Loading Capacity of Braced Domes
The stability behaviors of a practical latticed dome with 40 metres span are studied in this paper. The geometric and material nonlinear behaviors, as well as the effects of the initial...

The Georgia Dome and Beyond: Achieving Lightweight - Longspan Structures
In the last two decades, the development of longspan roof structures has undergone a quantum leap. The introduction of steel structures, fabric structures, Bucky Fuller's tensegrity structure,...

Effects of Spatial Triangulation on the Behavior of Tensegrity Domes
A number of long span 'tensegrity' dome type structures have recently been realized pursuant to the inventions of R. Buckminster Fuller and David H. Geiger. These structures have demonstrated...

A Practical Design and Construction of Tension Rod Supported Glazing
In designing a glass skin-covered space, for the atrium, entrance hall or other core part of a building complex, the high openness and quality requirements of the space often lead to the...

Elasto - Plastic Analysis of Cable Net Structures
This paper presents a Newton-Raphson interaction technique which takes account of plastic cable strains while iterating on the nodal equilibrium equations of cable net structures. The...

Multiobjective Optimization of Actively Controlled Structures
A general methodology is presented for the multiobjective optimization of actively controlled structures. The methodology can handle structures involving precise as well as fuzzy data....

Simulated Circulation and Transport in Adjacent Wind-Driven Estuaries in North Carolina
The Pamlico and Neuse River estuaries, in North Carolina, display similar physical characteristics because of their proximity and physiographic setting. Yet, because of channel configuration...

Simulation of Flushing in Indian River Lagoon Using 1-D and 3-D Models
Indian River Lagoon is a long and narrow estuary along the Atlantic coast of Florida. It is connected to the ocean via three relatively narrow inlets from the north to the south: Sebastian...

Modeling Circulation and Salinity Transport in the Indian River Lagoon
This paper presents preliminary results form a hydrodynamic and salinity transport modeling study of a section of the Indian River Lagoon near Melbourne, FL. The study is motivated by...

Tributary Loading with a Terrain Following Coordinate System
The modeling of physical processes that occur in a tributary between the farthest downstream gage and the lake interface can help to improve the predictive capabilities of Great Lakes...

Operational Interactive Hydrologic Forecasting with the National Weather Service River Forecast System
The National Weather Service River Forecast System (NWSRFS) consists of several major hydrometeorologic subcomponents to model the physics of the flow of water through the hydrologic cycle....

BPA Realtime Hydrologic Forecasting System for the Columbia River Basin
Bonneville Power Administration (BPA) markets and distributes the hydroelectric power produced at 30 federal projects in the Columbia River Basin. In order to plan the System's coordinated...

A Satellite Based River Forecast System for the Nile River
The initial version of the Nile Forecasting System developed by NOAA was used operational in July, 1993. Forecast System accuracy exceeded expectations. The Nile Forecast Center is now...

Optimization of Reservoir Releases to Control River Sedimentation Using Differential Dynamic Programming
A new methodology is developed to address sedimentation control in alluvial rivers downstream of reservoirs. An optimization model is posed as a discrete-time optimal control problem to...

Alameda Creek Water Resources Study
San Francisco Water Department is investigating water management policies for Alameda Creek to enhance both water development and fisheries. Preliminary investigations indicate that an...

Managing Reservoir Storage for Fish Production
Salmon populations in numerous Pacific Coast rivers are in decline and are in danger of becoming threatened or endangered. A reservoir system simulation model was developed for the Trinity...

Optimization and Reservoir Operations for the Missouri River
As demands placed on the operation of the nation's reservoirs increase, the problem of finding the most desirable set of operation plans becomes more difficult and controversial. This...
