The bending schedule end to end

One small job, a beam, a column and a footing, followed from the calculators to the project schedule, the project board and STATIX 2D, and the checks to make before a schedule goes to the bender.

1. Learning outcomes

After this lesson you can:

send elements from the calculators to one project schedule;
read and print the project schedule, with marks, members and mass;
say what the project board and STATIX 2D add;
check a schedule: counts, lengths, shapes and leg minimums, mass by size.

2. Before you start

Lessons 2 to 5, and RC Design 1, lesson 8.
The project schedule and the STATIX 2D tutorial.
About 45 minutes.

3. From the calculators to one schedule

The routes from a design to the bending yard in STATIX. The calculators feed one project schedule with their “Add to project schedule” button; the project board puts it on sheets with quantities; STATIX 2D draws and schedules inside AutoCAD. Every route uses the same SANS 282:2011 catalogue.

“Add to project schedule”. Each concrete calculator sends its bar marks to the one project schedule. Adding the same element again replaces its rows, so the schedule follows the design; the number of members multiplies an element that repeats.

The project schedule page: member, bar mark, type and size, number of members, number in each, total, length each, shape code and sketch, the A to E dimensions and r, and the mass. Each member group shows its mass, and the foot of the table totals the mass by bar size. It prints to PDF with the contract, drawing and checker fields filled in.

Bar marks. One series runs through the whole project, so a mark means one bar shape and size wherever it appears; the project board can renumber the marks in element order after changes.

Mass. Each row’s mass is the total number of bars times the cutting length times the mass per metre (πφ²/4 × 7 850 kg/m³); the schedule adds them up by bar size, which is what the steel is ordered and paid by.

4. Sheets, the project board and STATIX 2D

The project board collects the elements on drawing sheets with one bending schedule: the schedule for the steel fixer as a PDF, an order list as CSV, a cutting list from 12 m or 6 m stock bars, sheets as PDF or DXF, and a drawing register. It is part of the calculator packs (on sale soon).

STATIX 2D for AutoCAD, as its tutorial walks through it: set covers and the stock length once, detail each element with a wizard, check the rows in the Scheduler (warnings in the Err column), then publish schedule layouts and export to Excel or PDF. It is released for paid accounts, with a 30-day trial.

What is free and what is not: every calculator’s result is free. Signed in, three designs a month include the calc sheet and the bending schedule. The calculator packs (on sale soon) unlock calc sheets, schedules, drawing sheets, saved work and the project board. STATIX 2D is released for paid accounts, with a 30-day trial.

5. Checking a schedule before the bender

Checking the counts. Bars at a spacing across a width are the width divided by the spacing, rounded down, plus one: a first and a last bar. Count links the same way over the length they cover, and multiply by the number of members.

The length limit. Bars come in stock lengths, and the catalogue caps a scheduled bar at 13 000 mm; a longer run is split into bars with a lap, placed in a low-stress zone. STATIX 2D lists the bars over its stock length for you.

Checking the shapes. Each shape code has minimum legs in the SANS 282:2011 catalogue; a shorter leg cannot be bent on a standard former. Check the codes are 2011 codes (no 35), the radius is standard or carried as 51 or 99, and every leg meets its minimum.
