Abstract
This paper is concerned with the development of a
knowledge-based system for the economical design of
tubular trusses using a fabrication-led approach. This is
achieved using, in addition to structural design and analysis
modules, a cost model. The cost model was developed using
mainly the object-oriented methodology. It can be used for
estimating the cost of fabrication of one or a number of
trusses, joint detailing, members and individual fabrication
operations. Therefore the relative cost of one design option
compared with its alternatives can be obtained. Using the
model, the designer can also assess the sensitivity of a cost
item on certain design parameters.
