Analysis of Geometric Mispositioning in a Vertical Pile Group
A straightforward procedure is described whereby an approximate, three-dimensional, nonlinear model for the analysis of pile groups is used to simulate errors in major group parameters...
Development of a New Hydraulic Design Tool for Spiral Casing/Distributor Geometry
A novel computational model has been developed to predict highly complex turbulent flow in a combined spiral casing/distributor geometry. Validation of the computational model against...
Finite Element Reliability of Two Dimensional Continua with Geometrical Nonlinearity
First and second-order reliability methods and the finite-element method are combined into a general methodology for reliability analysis of complex structures with uncertain characteristics...
Random Vibrations of Geometrically Nonlinear Finite Element Plates and Shells
A finite element formulation combined with stochastic linearization and normal mode methods are developed for the study of geometrically nonlinear random vibration characteristics of plate...
Dynamic Stability of Cable Domes
The cable domes designed by David Geiger for the gymnastics and fencing arenas for the Olympics at Seoul, Korea, and for the stadium at St. Petersburg, Florida, are geometrically non-linear...
Geometrical Nonlinearity in Offshore Pipelines
Pipelines are very flexible structural systems which are subjected to various boundary conditions. For instance, during the laying process, the pipes roll on the guidance tracks on the...
Brick Design for the Lunar Surface
Force and Geometry Constraints in Robot Excavation
One interest in this research effort was to develop and test an automatic control approach to adjust machine motions to the force conditions encountered during excavation - essentially...
Fractal Dimension of Cracks Found in Drying Sludge
Study on Hydrologic Response Via Channel Network Geomorphology
A drainage basin consists of slopes and channels. Slopes are the main fields at which rainfall input is converted into discharge. Stream-channels are the main fields at which the discharge...
Variational Method in Fluvial Hydraulics?A Review
The theoretical base of the principle of minimum energy dissipation rate and other related stationarity hypotheses have been reviewed. Recent applications of the theory to the calculation...
Hydraulic Geometry of Mississippi Hill Streams
Hydraulic geometry data based on field and office studies are presented for a series of streams in the Black Creek and Long Creek watersheds in the upland hills of Central and Northern...
Blocking of Layered Flows in Channels of Gradually Varying Geometry
Issues of Rate Structure, Scaling, and Aggregation in Ecological Risk Analysis
Form Follows Geometry
The $107 million NCNB Plaza in Tamps, Fla. consists of a 32 floor, 500,000 sq ft, 455 ft tall office tower; a 40,000 sq ft, 78 ft tall banking hall, and a 280,000 sq ft parking garage...
Designing in Circles
Round buildings are a popular�but sometimes expensively perceived�design choice. With careful engineering and planning, they can offer a creative, cost-competitive option. They add another...
Geometric Non-Linearities in Cable Tray Assembly Seismic Response
Presented in 3-D
Stone & Webster started development in 1985 on a mainframe based computer system that provides the capability to integrate all plant information into a single integrated plant...
Constraint Based Design from Research into the Classroom
Design is constraint oriented; much of the design process involves the recognition, formulation and satisfaction of constraints. Constraints are continually being added, deleted and modified...
A Minimal Input Computer Aided Manufacturing Program for Personal Computers
The author presents here an algorithm developed in Pascal for an integrated two and a half dimensional CAD/CAM system. The geometry and the tool paths are defined simultaneously, thereby...
