An orthogonal cable network with hyperbolic paraboloid shape is subjected to point loads.
Determine the displacements.
The roof is modeled by a finite element mesh of 80 cable elements and 41 joints. The joints on the outer boundary are fixed.
The material and sectional properties of the cables are:
Modulus of Elasticity = 24,000,000 lb/in2
Area = 1.0 in2
