This is a structural glass assembly consisting of a series of specially processed glass panes, bolted together at their corners by means of ‘spider fittings’ or ‘metal patch fittings’ along with silicone sealant at the pane-to-pane joints. The minimization of metal framing members creates an effect of transparency that forms a natural and artistic blend between the indoor space and the outdoor environment. Different methods can be used to support the dead-load of the system and to provide lateral stiffness against wind-loading. Depending on the method used, the system is sub-divided into:
The glass facade and glass fin is connected using stainless steel spiders. The top of the glass panels/fins are supported at the top, in order to withstand the dead-load of the system, either using bolts/welds (if steel) or anchor-fasteners (if concrete). Consecutive Glass fins are connected using bolted splice plates.
Tension Rod System: The composite structure is set up with the of ‘tension rods’ (stainless steel pipe structural members designed to always be in tension). The tension-rod structure withstands the exterior loading on the glass facade.
All the loading on the glass facade is transferred by means of stainless steel ‘spider fittings’ to a steel structure erected independently behind the facade.
A system of geometric non-linearity is set-up with the use of pre-stressed tensile cables that withstand the exterior loading on the facade system. The vertical cable also withstands the dead-load of the system.
This system is further subdivided into Cable Truss Systems and Cable Net Systems.
