ABSTRACT
Several attempts have been made to optimize the design of bridge and roof trusses. This work
presents the development of an Expert System (ES) for the optimal design of bridge trusses
subjected to moving loads and roof trusses as well. The research improves on such previous
attempts in many areas including automation of structure data generation, experience gaining
facilities, suggestions and decision making, flexibility, and structural arrangement, shortest
possible volume of input data, ability to carry out self improvement, and dependability for
professional adoption. Least-weight truss optimization which translates to least-cost design was
achieved for the truss configuration for any given span of trussed bridge or roof truss. The
objective function necessary for minimal weight of structure subject to serviceability
constraints was derived. Five classes of bridge and roof trusses considered are the Warren,
braced Warren, N-, Pratt and braced Pratt trusses. The bridge trusses are arranged to take loads
from the bridge deck through stringer and floor beams to the joints. The expert system was
encoded based on appropriate design codes and rules of thumb garnered from experienced
professional engineers. The system initializes its knowledge base for spans and loads of
sufficiently wide ranges in both cases. The objects of the database include the optimum truss
types stored in memory with coded numbers to maximize storage memory. The knowledge
base expands with use, which makes the expert system to become more intelligent. Evaluation
of the performance of the developed system demonstrates high accuracy, efficiency, savings in
data entry, computational time and ease of reuse. The compiled form of the resulting product is
useable on all forms of digital computers. Comparison of its results with those of popular
industrial software demonstrates its superior performance in all cases.
