Cable-Stayed Structures: A Brief

les are the main supporting elements of the structure, and their curvature is a m generically is used to describe a flexible tension member consisting of one or m a central wire in one or more symmetrical layers. A wire “rope” is made from mult because ropes are more flexible than strands.

Cable Nets

e steel pylons, steel cable networks, steel or wooden grids, and roof coverings of

Structural Characteristics

carry the dead load, but must also have enough reserve capacity to carry the live ormal force created by the upward pull of the stays. The stays are usually attach r or column. or box beam. The box beam is advantageous because resists torsional forces well; h d by the first stay is built next. In a similar fashion, the remaining pieces are

Structural Characteristics

e upper end of all of the the stays attach to a single point at the top of the to llel system of stays, each stay is parallel and thus connects to the tower at a d

Also the each of the acrylic plate rest on the net structure which is also made up of steel cables passing horizontally as well as laterally. None of the joint is continues with each other In order to gain more stable form .
