Abstract
In the paper the prototype of the knowledge-based expert system ESAS for the evaluation of the seismic resistance of RC
buildings is described. The system runs on IBM PC's and compatible personal computer under a MS-Windows environment.
Hybrid knowledge representation is used. The system performs three different groups of tasks: (1) Evaluation of the conceptual
design, (2) Control of the results of analysis and, (3) Assessment of seismic safety. Two different levels of sophistication are
available to the user. At the first level compliance with EUROCODE 8 is checked, whereas at the second level different sources
of knowledge published in the literature and provided in different codes are included. One of the outstanding characteristics of
the system is the use of neural network-like non-parametric regression for the determination of the seismic capacities of structural
elements. A hypothetical 12-storey RC building is used as a text example, illustrating some characteristics of the system.
