Abstract
The objective of the present thesis is to develop a
knowledge-based expert system computer program, written in
symbolic language (TURBO PROLOG), capable of providing the
designer engineer with the feasible solutions (arranged from best
to worst) of the flooring structural system (location of columns,
beams and slab types) of a given architectural plan of common
residential buildings. Another developed kowledge-based expert
system computer sub-program is introduced to complement with the
main previously described system. This sub-program is written
also with the same conceptual language, to give the best feasible
solutions of concrete dimensions of different structural elements
(slab, beam and column) and the corresponding area of required
steel associated with steel bars and diameters according to the
Egyptian code of practice recently developed using the Limit
States Design Method.
The thesis includes a general introduction for expert
systems and artificial intelligence and their using in civil
engineering field is introduced. Also literature survey is
presented for some published researches concerning the expert
system applications in civil engineering field and explanation of
most different assumptions which have been considered in these
researches Description of the main outlines of the developed floor
expert system is presented. The main concepts of the system are :
Specification of the given architectural plans, depth search
level to find the possible structural solutions, probability tree
concept at each depth search level, definition of floor
structural elements through differen~ solutions, calculation of
approximate quantities of structural elements at each feasible
solution, evaluation of each solution via an evaluation factor
and calculation of comparison factor of each feasible solution.
There are many applications on practical architectural plans
which were analyzed by the program for their best structural
solutions. Also there are many practical sections (columns-beamsslabs)
which have been designed using the developed knowledge-
based expert system computer sub-program to get the feasible
solutions.
