Galt Energy's Inverted Siphon System
Galt Energy Systems' involvement with attempting to standardize the civil component began with studies at small remote sites in Northern Ontario. The system design evolved...
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...
Finite Element Analysis of Concrete Armor Units Subject to Wave Impact
Concrete armor units are commonly employed for the protection of shorelines and rubble structures. Their design is primarily based on hydrodynamic stability. However, their structural...
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...
Dynamics of Machine Foundation
The art of designing machine foundations, supporting vibratory load has changed from the approximate rule-of-thumb to the scientifically sound engineering procedure. However, the vast...
Dynamic Soil-Structure Interaction by the Boundary Element Method: A Comparison Study
A comparison study of three Boundary Element Method approaches is attempted on the basis of a typical three-dimensional, dynamic soil-structure interaction problem. The vertical transient...
Solving Finite Element Structural Dynamic Problems on Small Computers Using Semi-Explicit Methods
Numerical techniques based on the partial decomposition of a coefficient matrix, are developed for structural dynamic problems. Improved iterative techniques are discussed which could...
The Lanczos Method in Structural Dynamics
The solution of the equations of motion often results in the solution of an eigenvalue problem in which the system matrices are large. Traditionally, the solution of this problem has employed...
Response of Eccentrically Braced Tall Buildings
The inelastic dynamic response aspects of tall steel buildings with eccentric K-bracing and eccentric X-bracing systems are examined, when subjected to factored El-Centro and computer...
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...
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....
Animated Response of Dynamic Systems
Understanding how a simple structural system responds to a dynamically applied load is a difficult concept for most students to grasp. The fundamental mathematical theory of this behavior...
Seismic Risk Analysis of LNG Storage Tanks
This paper presents an approach to the seismic safety review of existing LNG storage tanks. The approach considers the seismic hazards from ground motion, surface fault rupture, and soil...
Attaching Steel Members to Reinforced Concrete Elements
A variety of structural systems have been devised to strengthen existing buildings for improved seismic resistance. Strengthening methods currently in use for reinforced concrete structures...
New Techniques in Forced Vibration Testing
Forced vibration testing is a well established technique as indicated by references 1 to 8. This paper describes a system for forced vibration testing developed over two years during work...
Sequential Earthquake Response of an Earth Dam
Sequential earthquake-response records of the well-instrumented Long Valley earth dam (Mammoth Lake area in California) are analyzed and engineering interpretations are made. The dam,...
Evaluation of Building Response Recorded During the Morgan Hill Earthquake
On April 24, 1984, the Morgan Hill Earthquake (Richter magnitude 6. 2) occurred within approximately 15 km of IBM Corporation's computer-equipment manufacturing facility located...
Dynamics of Fender and Rack Systems for Docking Ferries
A dynamic analysis of a ferry fender and rack system is developed based on the conservation of energy principle and Newton's laws of motion. The dynamics of the interaction...
Dynamic Testing of Structures Using the RESCUE Technique
This paper describes the most recent phase of an NSF supported program at SRI International to develop the technique of repeatable earth shaking by controlled underground expansion (RESCUE)...
Pseudo-Dynamic Testing of Structural Components
The pseudo-dynamic testing procedure is a simultaneous simulation and control process in which inertia and damping properties are simulated and flexibility properties are acquired from...
