Ring Beam
Explains the ring beam's tying function, which is what distinguishes it from an ordinary perimeter beam.
Educational reference entry. What this element has to do, and whether any particular arrangement of it is adequate, depends on the whole assembly, the loading, the exposure, local requirements, the manufacturer's instructions and qualified professional design.
Overview
What a ring beam is
A ring beam runs continuously around a structure at one level. It does two things at once: it spreads load arriving from above onto the walls beneath, and it ties the walls together so they act as a box rather than as separate panels.
The tying function is the one that is easy to overlook. A wall on its own can be pushed outward; a wall tied at its head into a continuous ring is restrained by the walls at right angles to it.
Boundaries
How it differs from nearby elements
The distinctions that keep this entry from being a restatement of its neighbours.
- It is not an ordinary beam. An ordinary beam spans between supports; a ring beam sits on continuous support and its purpose includes tying rather than spanning.
- It is not a wall plate. A wall plate spreads bearing from members above onto masonry; a ring beam is a structural member in its own right and provides restraint the plate does not.
- It is not a lintel, although a ring beam commonly passes over openings and can be designed to do both jobs.
Terminology
Common names and aliases
These names describe the same element. The library keeps one entry per component so that a trade term or a regional name never becomes a second, thinner page.
- ring beams
- tie beam
- perimeter tie
Dependencies
What it depends on
What has to be right elsewhere for this element to do its job.
- Its continuity around the structure, since a ring that is not continuous does not tie.
- Its connection into the walls beneath and the structure above.
- How corners are handled, because the corner is where the tying action is actually developed.
- Whether openings interrupt it, and how that interruption is dealt with.
Considerations
Topics that genuinely apply here
Subjects worth discussing about this element. These are discussion topics, never measured values, ratings or performance claims.
It spreads concentrated loads from roof or floor members onto the wall beneath rather than letting them arrive at points.
Tying walls together changes how the structure responds to loads that would otherwise push individual panels outward.
Continuity through corners and past openings is where ring beams are commonly compromised on site.
A continuous concrete or steel element around a building perimeter sits across the insulation line, which is a thermal-bridging question for the envelope design.
Materials
Commonly formed from
Material families this element is commonly realised in. This states common practice only — it is not a statement that any of these materials suits this component in a particular building, which depends on the whole assembly and on qualified review.
Materials
Commonly incorporates
Materials this element commonly contains as a distinct constituent part, rather than being made of.
Assemblies
Building systems this element is met in
The role this component fills inside each assembly. A role describes what the element does there — it is not a statement that this component suits that system in any particular building.

Clarifications
Commonly misunderstood
- That a ring beam is only about spreading load. The tying function is frequently the reason it is there.
- That it can be interrupted freely at openings. Interruptions have to be designed, because a discontinuous ring has lost part of its purpose.
Conversations
Questions for qualified professionals
Questions worth asking someone with the project in front of them. This page cannot answer them.
- What is the ring beam here doing — spreading load, tying the structure, or both?
- How is continuity maintained at corners and across openings?
- How is it connected to the walls beneath and the structure above?
- How does the envelope design deal with this element crossing the insulation line?

What this entry does not do
- No section, reinforcement, continuity detail or capacity is stated here.
- Whether a ring beam is required, and what it must do, is structural design work.
