SpletA major distinction in scaffold structures are those made from prefabricated components such as Cuplok [19, 20] or modular scaffolds such as the ‘door-shaped’ ones often used in the US and Asia [21] and scaffolds made from steel tubes (called tube-and-fitting scaffolds) [22] or bamboo [23]. Proverbs et al [24] compared French, Splet01. jan. 2005 · For its stiffiiess normal to the fa9ade the scaffold is dependent on the presence of the ties and their frequency. The more common type of tube and fitting access scaffold is the independent tied scaffold. This scaffold is independent of the fa9ade to the extent that it carries all the vertical loads and does not transfer any to the fa9ade.

A frame is considered to be non-sway (braced) if it is sufficiently braced by lateral bracing elements like structural walls. On the other hand, frames that provide lateral resistance only through columns are considered to be sway frames (unbraced). ACI 318-19 can be used as a reference to distinguish between sway and ...
