Lesson 6 of 6
Produce and check a complete beam schedule
Assemble stirrup, bottom-bar and top-bar rows, total the steel and use density as a reasonableness check.
This builds on Lesson 5, where we worked out development length, stock pieces and lap steel — go back to Lesson 5.

Add all three rows
Sum unrounded row weights, then round the displayed total. No wastage or stock splices are included.
Stirrups only
39.04 kg
This is only the S1 row. Main-bar steel still belongs in the schedule.
Whole schedule
195.48 kg
S1 + B1 + T1 = 195.48kg across all 3 beams.
Learn · Part 3
Check the scale of the answer
A density comparison prompts review. It cannot prove structural adequacy.
Steel density
157.39 kg/m³
195.48kg / 1.242m³. The calculator’s indicative beam range is 100–200kg/m³. Within that range; still check every drawing input.
Apply what you learned
Your turn.
Add the displayed S1, B1 and T1 row weights below. What is the total steel weight, to two decimal places?
See the worked solution
S1 39.04kg + B1 78.22kg + T1 78.22kg. Display rounding can differ slightly from a total of unrounded rows.
Answer: 195.48 kg.
Lesson notes & reference
Worked exampleThe complete worked schedule totals 195.48kg for 3 identical beams.

The schedule you’re building toward
The same worked example throughout the course: three identical beams, with three bottom and three top main bars in each.
| Bar | Shape | Dia | Cutting length | Bars per member | Total bars | Total length | Weight | Notes |
|---|---|---|---|---|---|---|---|---|
| S1 | Stirrup · rectangular, 135° hooks | 8mm | 1220mm | 27 | 81 | 98.82m | 39.04kg | Uniform centres; no zones |
| B1 | Bottom main · straight | 16mm | 5500mm | 3 | 9 | 49.50m | 78.22kg | Straight anchorage at both ends |
| T1 | Top main · straight | 16mm | 5500mm | 3 | 9 | 49.50m | 78.22kg | Straight anchorage at both ends |
Total steel: 195.48kg. Worked quantities exclude wastage. Main bars assume straight anchorage fits each support; use the actual structural detail for a project.
