An Integrated Knowledge System of Seismic Vulnerability and Risk for Engineered Facilities
This paper describes an integrated knowledge system for the assessment of the seismic vulnerability and risk of engineered facilities. The system integrates knowledge from many fields...
A Knowledge-Based System for Evaluating the Seismic Resistance of Existing Buildings
The large number of existing buildings designed without considerations of seismic loading warrants the development of computer aids for the evaluation of their seismic resistance. Since...
Vector Optimization of Structural Systems
In this paper the basic ideas of vector optimization are presented, and both the weighting and constraint methods are applied to vector optimization of truss systems by minimizing the...
Concrete Lunar Bases
Scientific and industrial operations on the moon require suitably shielded structures. Small structures for limited scientific activities may be constructed from structural elements prefabricated...
Fatigue Evaluation of a Riveted Railroad Bridge
An 83 year old railroad bridge was analyzed for fatigue based on historical records such as the original schedules. Based on the number of cycles to date, corresponding to an effective...
Water Transport in Limestone by X-Ray CAT Scanning
The transport of water through the interior of Salem limestone test briquettes can be dynamically monitored by computer aided tomography (commonly called CAT scanning in medical diagnostics)....
Service Life of Underground Concrete Structures
The service life of underground concrete depends on both the physicochemical properties of the concrete materials and the properties of the in-service environment. The major factors controlling...
Predicted Fatigue Life Behavior of Stay Cables
Monte Carlo simulation results are used to illustrate the relationship between the fatigue lives of short prestressing strand test specimens and long strand stay cables. Long stay cables...
A Summary and Review of Fatigue Data for Mechanical and Welded Splices in Reinforcing Bars
Published reports pertaining to fatigue tests of welded and mechanical splices in reinforcing bars were reviewed. It was observed that most specimens fractured in the reinforcing bar adjacent...
Inspection Strategies for Offshore Structures
The fatigue limit state is the governing limit state for the structural dimensions in several parts of offshore structures. Prediction of the fatigue life of tubular joints and other welded...
Effect of High Frequency Response on Fatigue of Offshore Structures
