Abstract
The goal of this investigation is to design minimum
weight arch structures which span the distance between two
points in two-dimensional space. An arch of unknown shape and
variable cross-sectional width is modeled as a series of
straight bar-beam elements. Finite Element Methods are used
to compute the stresses in each element. Automated Design
Synthesis (ADS) software is then used to vary the slope of
each element and the cross-sectional width to prevent the
yield stress of the material from being exceeded as ADS
minimizes the arch volume to arrive at the minimum weight
structure. Results are presented for a number of different
loadings and boundary conditions.
