Structural glass from 1990 to today

How structural approaches to glass design developed from 1990 to the present — and how the rules governing structural glass moved into the public domain.

On September 15, 17:30, WTC Yerevan hosted a Catalyst talk with Timothy Macfarlane, Chartered Engineer (CEng), Member of the Institution of Structural Engineers (MIStructE), Royal Designer for Industry (RDI), Honorary Fellow of the Royal Institute of British Architects (Hon FRIBA), Honorary Fellow of the Royal Incorporation of Architects in Scotland (Hon FRISA).

Tim Macfarlane has been a leader in the innovative use of glass as a structural material for over 30 years, contributing to complex projects ranging from small bespoke glass installations to large-scale frameless glass assemblies, including pioneering the use of structural glass in the original Apple Flagship Stores in New York, Chicago, and San Francisco—an engineering sophistication that set a standard for the further development of Apple stores worldwide. Tim Macfarlanefounded Dewhurst Macfarlane and Partners with Laurence Dewhurst in London in1985 a partnership which developed over a period of 27 years into aninternational practice with offices in London, New York and Trinidad.

The presentation traced the development of structural approaches to glass design from 1990 to the present time.

The engineering properties of glass once jealously protected by manufacturers in the private domain has since 1990 gradually infiltrated the public domain providing a valuable tool for architectural and structural designers.  

The talk illustrated through key projects the process of bringing this key knowledge to light enabling the rules that govern the structural engineering use of glass to be used by everyone.
