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...
The 1983 Landslide Dam at Thistle, Utah
The Thistle, Utah, landslide began rapid movement on April 13, 1983. The landslide, a reactivation of an estimated 22 multiplied by 10**6 m**3 of old landslide debris, blocked Spanish...
What is an Expert System
Knowledge-based expert systems (KBES) have created much excitement in the civil engineering computer user community. KBES evoke expectations of full-blown Artificial Intelligence (AI)...
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...
RC Structures Under Severe Loads?An Expert System Approach
The authors propose the application of expert systems to the post-test assessment of specific structural systems. In the study reported, an existing expert system shell was employed and...
DAPS: An Expert System for Damage Assessment of Protective Structures
An automated reasoning code for the damage assessment of protective structures (DAPS) is being developed within the Air Force. Protective structures in this context will be synonymous...
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....
