An Economical Approach to Receiving Coal by Rail in the Sub-Arctic Environment
During the period 1983 to early 1985 a multimillion dollar coal transfer facility was designed and constructed in Seward, Alaska. The facility transfers coal from rail cars to temporary...
Finite Element Modelling of Cold Regions Concreting
Finite element heat transfer computer programs are discussed in regard to their use in modelling cold weather concreting. The concrete material properties required for input to the finite...
The Transport of Crude Oil Under Saline Ice
A mathematical model was developed to describe the forces acting on an oil slick under saline ice in the presence of a water current. The model was verified through a set of laboratory...
Moisture Effects on Extruded Polystyrene Insulation
The amount of moisture within the insulation was determined by carefully weighing each sample and then measuring its volume. Two methods of measuring thermal conductivity were used. The...
The Evolution of a Factory Insulated Piping System
This paper reviews the developments over the past fifteen years in a factory insulated high density polyethylene piping system that has become a standard for sewage and water piping systems...
Insulation Performance Beneath Roads and Airfields in Alaska
Evaluations of the long-term thermal performance of installations in Alaska for frost heave control have included sampling and testing of the insulations to determine the retained thickness,...
Expert Opinions and Expert Systems
The inference mechanism in most current expert (rule-based production) systems is based on exact matching of the antecedent or consequent of a rule with a fact or hypothesis. The rule...
Applications of Artificial Intelligence in Preliminary Structural Design
The field of Artificial Intelligence (AI) deals with the problems of modeling human intelligence. The application of AI to structural engineering has been limited, but potential applications...
Broke2: A Program for Broken Wire Analysis
A computer program to study the dynamic behavior of an electric transmission line system when wires suddenly break has been developed by the authors. All three of the line elements: the...
Measuring Dynamic Occupant Loads by Microcomputer
Present building codes regard live loads caused by human movement as deterministic; values are based upon experience and tests run in 1912, 1922, and 1932. An experimental project to statistically...
Structural and Architectural Maintenance Management by Micro-computer
When a new Senior Vice-President for University College, the nonmedical portion of the University of Alabama at Birmingham, was appointed in 1984, one of the problems encountered by the...
How To Design Highway Retaining Walls?A Practical Application of CADD
The recent work developed at the University of Missouri-Rolla (UMR) including optimization algorithms and two computer programs, ODSEWS-2D-II and ODRESB-3D are discussed. Several numerical...
Engineering Optimization Via Genetic Algorithm
The application of a genetic algorithm (GA) to the optimal design of a ten member, plane truss is considered. Genetic algorithms are search procedures based upon the mechanics of natural...
Design Improvements Using Finite Elements and Optimizing with Approximate Functions
A design optimization module has been added to the finite element program ANSYS, designed to aid the engineer in reaching an improved or optimum design. The numerical technique employed...
Incorporating Uncertainty in a Dynamic Structural Analysis
A methodology has been developed and exercised for taking into account parametric uncertainties in a structural dynamics analysis and providing an approximation of the probability of response....
Study of Structural Behavior with Computer Simulation
The application of computer simulated testings of structural elements in the civil engineering undergraduate education is described. With a computer simulation a structural component may...
Equation Solving on a Parallel Computer
The application of computers to the analysis of large structural systems is examined. The analysis procedure is presented as three distinct phases: (1) element formulation, (2) equation...
Accuracy Control of Finite Element Analysis of Articulated Structures
An examination of the properties of two-node element models leads to data establishing the acceptable choices in discretization to insure the accuracy of finite element analysis of articulated...
Rebuilding Mexico City
After the September 19, 1985 earthquake in Mexico City, officials had to cope with a massive volunteer effort to inspect damaged and destroyed structures. Over a thousand engineers, contractors,...
