LimitState:RING
LimitState:RING is the leading software for the rapid analysis of masonry arch bridges. Used by engineers worldwide, it enables the assessment of bridge capacity using rigorous, proven limit analysis methods. With an intuitive interface and powerful modelling capabilities, LimitState:RING helps streamline assessments, optimise rehabilitation strategies, and ensure the resilience of these historic masonry structures.
Designed to support assessments in line with CS 454 and CIRIA C800, LimitState:RING v4 incorporates Permissible Limit State (PLS) assessment, enabling engineers to assess structures against serviceability criteria in addition to ultimate limit state conditions. With clear, engineering-focused outputs, LimitState:RING v4 helps bridge assessors make informed decisions while ensuring compliance with the latest industry standards.
