Archie-M

Archie-M is a Windows program (Windows NT/2000 and XP) designed to help with the analysis of masonry bridges and viaducts. It is based on the principle of the thrust line, but goes rather farther than that. It can be used as part of the assessment or design process.

Archie-M provides rapid, interactive equilibrium analysis of arching structures. The program is a result of nearly 20 years of research and consultancy.

Archie-M uses the zone of thrust to define the minimum structure necessary to support a given set of loads. Graphical and numerical results are updated continuously as loads are moved across the structure by hand or automatically. The engineer is able to explore the potential for different load paths to transmit loads to the foundations.
