The use of expert systems in seismic risk analysis

ABSTRACT

Regional damage estimation is a necessary step in the seismic policy process, which is aften hampered by a lack of information on the seismic resistiveness of building and other structures. This paper describes an experts system for determinig the construction type of buildings, based on information obtainable from a visual inspection. The expert system of incorporated in a computer program for estimationof seismic damage to buildings. Several approaches are considered in the development of the expert system, including the use of special types of neural nets, and treatment of uncertainty using both Bayesian Probability models and Dempster - shafer Calculus (AU)
