Abstract
This thesis is an investigation of the static response of three
dimensional cable structures. The thesis introduce an extensive
survey of published work on general concepts, historical and
structural types of three dimensional cable roof structures.
A numerical procedure for the static analysis of highly
nonlinear skeletal structures based on minimization of the total
potential work has been extended to account for the structural
components of cable roof structures. The material and geometric
nonlinearities effects are accounted for in the method through an
iterative procedure. Different clad roofs have been investigated
representing the clad roof element as a plate element. This
investigation shows the high performance and accuracy of the
algorithm. A simplified approach is proposed for representing the
clad plate element as two cross diagonal links.
The static behaviour of clad cable roof structures are
investigated as it is important to establish patterns in the structural
behaviour of cable roofs considering clad effect. An extensive
study on the static response of three different shapes of cable
roofs, i.e. flat, hyper, saddle shapes have been performed. The
effect of different parameters are investigated by using the
proposed methods. These parameters are shape, increasing load,
cable net to clad relative stiffness ratio. The results of this study
are discussed and summarized.
