Design of a Knowledge Based System to Convert Airframe Geometric Models to Structural Models
Airframe manufactures who use CAD tools to design airframes and finite element analysis software to analyze them, still generate the finite element models using semi-manual methods. Although...
An Expert System for Flood Estimation
This study was made to investigate the feasibility of expert systems for solving certain engineering problems. A prototype system was developed to demonstrate the applicability of these...
Developments in Expert Systems for Design Synthesis
The applicability of expert systems to design synthesis is demonstrated. This is achieved by means of inference rules which can interpret design specifications in order to produce designs....
Knowledge Engineering in Object and Space Modeling
This paper gives a description of Topology-1, which attempts to provide a tool for object and space modeling through the use of knowledge engineering techniques. It elaborates the system...
Qualitative Physics and the Prediction of Structural Behavior
A key need in the application of expert systems to structural engineering design is the ability to predict structural deformation and stresses in the absence of a quantitative model. The...
Manpower Planning?Make a Moral Contract
One key to manpower planning is forecasting realistic and accurate manhour projections for work in-house or work in the proposal stage. A method used by the author to project manhours...

Assessment of Safety Impacts of Highway Projects
In this paper the safety impact of highway improvement and maintenance activities is examined in terms of accident reduction potentials of these activities. There are three causes of accident:...
RRR Design Standards: Cost-Effectiveness Issues
The Transportation Research Board study of geometric design standards for RRR projects is currently trying to match the logic of cost-effectiveness to the mostly judgmental process of...
Location and Development of Safety Projects
Projects to be considered for inclusion in the Highway Safety Improvement Program (HSIP) must be part of a prioritized listing in which each project is based on accident experience or...
Evaluation?A Key to Safer Design Standards
Public highways are designed and constructed in accordance with established standards which have been developed over the years as a result of research studies or developed by committees...
Base Isolation in the Design and Construction of Power Plant Structures
This technical paper summarizes the results of some of the recent studies performed to assure technical feasibility in isolating safety-related nuclear power plant structures. The particular...
The Asbestos Impasse
Removing asbestos from the nation's buildings is a major task . Consulting engineers can play an important part in the process, locating and quantifying the carcinogenic material,...
U.S.-Japan Coordinated Program on Masonry Research
An overview of the U. S. -Japan Coordinated Program on Masonry Research is presented. The program consists of parallel efforts in Japan and the United States to develop design methods...
A Critical Look at Building Instrumentation in Earthquake Engineering
This paper discusses different issues and requirements existing in the area of building instrumentation. Strategies and types of equipment currently being used by the United States Geological...
Hysteretic Behavior of Composite Diaphragms
Floor systems constructed with steel-deck-reinforced concrete are described. When used to resist lateral loads these systems are referred to as diaphragms. A description of a test arrangement,...
Refinements in Pseudo-Dynamic Test Procedures
One of the major concerns in seismic testing is whether the loading conditions imposed on a structure adequately represent those that might occur during a major earthquake. Response simulation...
Use of Vibration Tests to Determine Lateral Load Paths in Medium Rise Buildings
A structural system identification procedure is described in which an initial analytical model of a building is modified until it predicts accurately the mode shapes and natural frequencies...
Seismic Behavior of Long-Span Cable-Stayed Bridges
Special features of the earthquake-response analysis of cable-stayed bridges, subjected to multiple-support excitation, are presented including a basis for calculation of seismic forces...
Seismic Response Analysis of Two Major Bridge Structures
The seismic response analyses of two major bridge structures have been conducted. In these two bridges, portions of the piles are either submerged in the water or free-standing within...
