LimitState:RING v4
LimitState:RING v4
LimitState:RING v4 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.

LSWEB23-7 - Introducing LimitState:RING 4. Better Masonry Arch Bridge Analysis
Discover some of the exciting features of LimitState:RING 4, including: * Highly flexible definition of bridge geometry, with an enhanced wizard and CAD import functionality to handle the most geometrically complex structures. * Enhanced handling of vehicle loading scenarios, including new automatic vehicle positioning functionality to expedite identification of critical load cases. * A Permissible Limit State (PLS) analysis mode to assess bridge performance under working loads. * Template file functionality to speed up the assessment of bridges with shared properties or project settings. * A command-line interface to support batch analysis. * Numerous other improvements, including an expanded vehicle database, new pre-solve diagnostics, and a greatly enhanced software user interface. In this 30-minute webinar, Dr Tom Pritchard and software originator Prof. Matthew Gilbert use practical examples to illustrate many of the new software features. Gain insights into how this significant upgrade can help you undertake more informed masonry arch analysis, helping to more reliably assess these critical components of our transport infrastructure.
LSWEB23-8 - Assessment of Highway Masonry Arch Bridges to CS454 & CIRIA C800 with LimitState:RING 4
n the UK in 2019 National Highways introduced a new standard for the assessment of highway bridges and structures, CS 454. In 2022 CIRIA published a long-awaited guidance document on the assessment of masonry arch bridges, CIRIA C800. LimitState:RING 4, the latest version of our industry-leading masonry arch bridge analysis software, offers a range of features to help streamline the assessment of masonry arch bridges in accordance with CS 454 and CIRIA C800. In this webinar, Prof. Matthew Gilbert outlines how LimitState:RING 4 simplifies the process of highway bridge assessment, including: * How use of the Permissible Limit State (PLS) facilitates more discriminating assessment of the performance of bridges under working loads. * Analysis of both the PLS and Ultimate Limit State (ULS) using LimitState:RING 4. * Use of built-in CS 454 load vehicles. * Use of template files incorporating CS454/CIRIA C800 specific settings. * Batch analysis using the command line interface. Practical examples are used to highlight the key features of LimitState:RING 4 that facilitate practical assessment of bridges in accordance with CS 454 and CIRIA C800. Discover how the software can streamline your workflow while delivering valuable insights into the likely behaviour of masonry arch bridges.
