Seismic Resistance of an Elevated Water Tank?A Case Study
Current knowledge of earthquake risk and structural response has raised concern about the safety of elevated water storage tanks which were constructed several decades ago. This paper...
Future Containerships from a Ship Owner's Viewpoint
This paper is a presentation of the author's projection of size and design constraints of future containerships. There is a discussion of containers and on-deck container...
Design and Construction of the Spirit Lake Outlet Tunnel, Mount St. Helens, Washington
In 1982, a governmental task force was formed to evaluate the hazard posed by the blockage of Spirit Lake that resulted from the eruption of Mount St. Helens in May 1980. An analysis was...
Problem Solving Using Expert System Techniques
There are basically two approaches to problem solving currently used in expert systems: the derivation approach and the formation approach. The derivation approach involves deriving a...
Design of an Expert System for the Rating of Highway Bridges
A microcomputer-based expert system used to determine the effects of vehicles and overloaded vehicles on simple span bridges with reinforced concrete deck and prestressed concrete I-beams...
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 for Construction Administration
Manpower planning is an important aspect of any organization, but is particularly difficult in an activity subject to as many variables as highway construction. This paper outlines a process...
Business Planning for Engineering Projects
Fluor Engineers is a full-service international engineering firm serving the process and energy industries. In conjunction with other Fluor subsidiaries, Daniel Constructors and Fluor...
Traffic Barriers: A Second Chance
More motorists are killed each year after striking traffic barriers than any other fixed object except utility poles and trees. These deaths occur primarily because the guardrail or bridge...
Enhancing Highway Safety Through 3R Construction
The safety improvement programs specifically aimed at correcting high accident locations (HALs) are certainly helpful. These programs have resulted in sizeable frequency as well as severity...
Non-Freeway Programwide 3R Accident Analysis: New York
The New York Program for restoration, rehabilitation and resurfacing (3R's) has relied on broad scoped projects and case-by-case consideration of exceptions to design standards...
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...
Delineation Effectiveness for Alcohol Involved Accidents
The approach to the problem of the alcohol impaired drivers to date has been directed at driver education and increased police enforcement. A complementary and parallel approach is presented...
Sighting Safety
This paper examines the interrelation between drivers' visual needs and the road environment. Specific elements of visual limitation and drivers at greatest risk are identified....
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...
