This paper presents a practising engineer's perspective on behaviour, analysis and design of cable supported roof structures. Particular attention is given to "hybrid" cable structures characterised by their interactive primary axial and secondary flexural systems. The issues of geometry and prestress are given some detailed treatment, and a methodology is proposed for analysing hybrid structures at their "as-erected" state. Global nonlinear analysis of the structure and the buckling analysis of its compression elements are also discussed. References are made to the recent projects designed by the author's firm.
