Simulation of River Ice Processes on Alaska's Susitna River
A numerical river ice model is applied to an 85-mile reach of Alaska's Susitna River immediately downstream of the proposed Susitna Hydroelectric Project. The model is designed...
Computer Modeling and Applications
A series of programs is available to evaluate the hydrology, compute the capacity to generate energy, establish unit costs, analyze penstock surge pressures, and simulate ramping rates....
Design of Drilled Piers Subjected to High Overturning Moments
The results are presented of a research study directed at improving the state-of-practice, and resulting foundation economy, in the design of laterally loaded drilled pier foundations...
Reinforced Roads Bridging Voids
A mathematical model was developed to design a pavement section reinforced with a geotextile or related product to span a void. A full scale field test was conducted to verify the model....
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...
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...
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,...
