LimitState:RING - Rapid Masonry Arch Analysis Software

Multi-Span Analysis

Automatically identify the critical collapse mode, whether this involves failure of one, two or more spans - no need to balance the thrusts exerted on pierheads by hand.

Vehicle Database

LimitState:RING ships with an extensive database of road and railway vehicles.

Users can also define their own custom vehicles and save them for use in other projects.

Validation

LimitState:RING is continually validated against high quality data from both small and full-scale laboratory arch bridge tests.

Users can therefore be confident that the output is as accurate as possible.
