Member Weight — Vertical Brace (HSS Pair)
Pick weight and rigging numbers for a vertical brace (hss pair) from unit mass and length.
Braces arrive late in the sequence by design — the frame needs to be plumbed BEFORE braces lock the geometry in. Flying them early freezes survey error into the building; this is sequencing, not strength.
Formula
Note: Erection-planning estimate only. Member weights, connection capacities and tolerances for execution must come from the issued drawings, the EOR and the erection engineer — never from a generic calculator.

About Member Weight — Vertical Brace (HSS Pair)
Member Weight — Vertical Brace (HSS Pair) computes the governing relationship W = kg/m × L × n × (1 + attachments) live as you type. Braces arrive late in the sequence by design — the frame needs to be plumbed BEFORE braces lock the geometry in. Flying them early freezes survey error into the building; this is sequencing, not strength. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.
How to use Member Weight — Vertical Brace (HSS Pair)
- 1Enter your values — Unit mass, Member length, Pieces per pick, Attachments (plates, clips) (sensible defaults are pre-filled).
- 2Read the live results: Pick weight, In tonnes.
- 3Check the "with your numbers" line to see W = kg/m × L × n × (1 + attachments) substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
Why use Member Weight — Vertical Brace (HSS Pair)?
- ✓Instant, free and private — every calculation runs client-side in your browser; nothing is uploaded
- ✓Built on the stated formula W = kg/m × L × n × (1 + attachments) with authoritative sources cited on the page (AISC 303 — Code of Standard Practice for Steel Buildings)
- ✓Braces arrive late in the sequence by design — the frame needs to be plumbed BEFORE braces lock the geometry in.
- ✓SI ⇄ Imperial toggle converts your inputs in place, so you can work in the units your drawings use
Frequently asked questions
What formula does the member weight — vertical brace (hss pair) use?+
It evaluates W = kg/m × L × n × (1 + attachments), exactly as published. Sources: AISC 303 — Code of Standard Practice for Steel Buildings. The substituted worked example on the page lets you verify every step against the textbook.
How should I read the result — and how far can I trust it?+
Braces arrive late in the sequence by design — the frame needs to be plumbed BEFORE braces lock the geometry in. Erection-planning estimate only. Member weights, connection capacities and tolerances for execution must come from the issued drawings, the EOR and the erection engineer — never from a generic calculator.
When is this calculator the right tool for the job?+
Pick weight and rigging numbers for a vertical brace (hss pair) from unit mass and length. A free structural steel delivery & erection tool. Flying them early freezes survey error into the building; this is sequencing, not strength. For neighbouring scenarios, the related tools below cover the same engine with different presets.
Does it support both metric and imperial units?+
Yes — the SI ⇄ Imperial toggle converts the values already in the fields, preserving the physical quantity, so you can flip mid-calculation without re-entering anything.
