The design of reinforced concrete beams involves the selection of design parameters such as beam

dimensions and reinforcement details which result in a safe and economical section. This process

of design consists of three stages: preliminary design, structural analysis, and detailed design which

includes the selection of dimensions, reinforcement, and stirrups. The design process is an iterative

one where considerable judgement and experience are required. This is an ideal situation for

the application of expert system technology.

A knowledge based expert system called BEAMDES was developed for the flexure design of reinforced

concrete beams in accordance with ACI 318-83 specifications. The expert system was developed

using the micro-computer based expert system shell, Insight 2+. BEAMDES can be used

to design both rectangular and tee sections. The beams can be simply supported, cantilevered, or


The results obtained from BEAMDES were tested against several example problems for both

supported and continuous beams. It was found that the designs recommended by the system were

similar to those of the examples.
