RING

RING 3.0 is the latest version of the popular software product for the analysis of masonry arch bridges - designed from the ground up with the needs of professional engineers in mind

Benefits

Flexibility and Power

• Analyse single or multi-span bridges with no fixed upper limit on the allowable number of spans
• Automatically identify the critical failure mode even if:
  • only a single span is involved
  • sliding is involved
  • modelling multi-ring arch bridges
• Define and solve for multiple load cases
• Automatically detect 'passive' pressures - analyse deep and multi-span arch problems without difficulty
• Model the presence of arch backing material

Ease of Use

• Easy to use wizard system for simple and speedy model definition
• Modern, intuitive interface with an interactive modelling environment
• Comprehensive library of standard road and rail vehicles
• Property editor allows quick querying and modification of model properties
• 3D graphical output for better understanding
• Automatic report generation

Specify Local Properties

• User-definable arch and backfill profiles
• User-definable individual block weights, masonry strength, mortar loss etc.

Proven Track Record

LimitState:RING is the product of many years research effort.

• The first version of the software was originally developed as an academic research tool in 1992, with results published in papers in The Structural Engineer and elsewhere
• The first public versions were developed in association with Network Rail
• Later versions were developed for worldwide use in association with the International Union of Railways (UIC)
