... The results are similar to these of circular cable nets as follows: a) Circular cable grids with the same arrangement ( n n × ) will act identically, i.e. ( L z S ∆ and S τ ) and 4 Due to this, equations from (4) to (9) are still valid for both sagging and hogging cables. a) For two circular grids ( 1 1 n n × ) and ( 2 2 n n × ), either concave or convex, with the same properties (diameter, steel area, loading, modulus of elasticity and sag (rise)/span ratio), approximate relations (11) and (12) are still valid, for both the suspension and the prestressed cables. Also, the forces in the hangers (struts or ties) are approximated as: This equation is satisfied as long as the steel area of the suspension cable is more than or equal to that of the prestressed cable ( ...
The main aim of the present work is to investigate the static analysis of circular cable suspended roofs, which are the most common forms of suspended roofs.
Many circular cable roofs have been analyzed using a computer program based upon the minimizing of total potential energy by the conjugate gradient technique. The results are used to investigate the factors that affect the design and the response of cable suspended roofs. Also, these results have been used in making non-dimensional tables and graphs and to infer new relationships. These tables, graphs and relationships form a good technique for the preliminary design of circular cable suspended roofs either nets or grids. This good preliminary technique was examined using several examples and the
results are in good agreement with these solved using the computer program based on minimizing the (TPE) using the (CG) technique for the analysis of cable roofs.
