# Beam Rebar — English tutorial

## 01 · Start in a 3D view
In this tutorial, we will reinforce a continuous concrete beam with BIMSpeed Beam Rebar. Start in a 3D view and make sure the beam and its supports are easy to see.

## 02 · Select the beam
On the BimSpeed Structure tab, open the Beam Rebar menu and choose Beam Rebar. Select the concrete beam, then click Finish. Here, one continuous beam passes through several supports.

## 03 · Set the main reinforcement
Quick beam reinforcement sets the starting layout. Choose the quantity and diameter for the main top and bottom bars. An already detailed beam can retain saved span values, so check those in the detailed editor. Use the reinforcement specified for your project.

## 04 · Choose additional bars and stirrups
Use these checkboxes when additional reinforcement layers are required. For this basic example, leave them unchecked. For stirrups, choose D eight and By zones. A one is the end spacing; A two is the middle spacing. This example uses one hundred and two hundred millimeters.

## 05 · Open the detailed editor
We will leave Create drawing sheet unchecked and focus on the reinforcement model. Click Edit details. The editor separates geometry, main bars, additional bars and stirrups. Open Geometry to check the detected width, height, span length and supports.

## 06 · Inspect a span
Click a span in the overview at the bottom to focus on it. The longitudinal preview now shows that span in detail. Use the section tabs on the right to inspect the reinforcement at different positions along the beam.

## 07 · Review the bar layout
Open Main Top Bar or Main Bot Bar to review the bar quantity and diameter for the active span. Use Apply to span when you make a change. The additional-bar pages are available when your layout needs extra top or bottom reinforcement.

## 08 · Review stirrup zones
Open Stirrup. Check the diameter, offset from the support face, end spacing and middle spacing. Review both end-zone lengths. Apply to all spans is useful when the same arrangement is intended throughout the beam. The preview helps you check the distribution before creating the model.

## 09 · Create reinforcement
When the layout is ready, click Create reinforcement. Allow Revit to finish creating the bars. This commits the reinforcement to the model; the editor preview alone does not create it.

## 10 · Inspect the result
Back in the 3D view, inspect the generated reinforcement. Use a close view to check the main bars and stirrup zones at the supports. Review any tool messages and check the result against your project's detailing requirements. That is the basic workflow: select, configure, preview, create and inspect.

# Beam Rebar — Main cases and settings

The opening lesson is followed by these case chapters. Values describe the recorded practice models. They are not a reinforcement design specification.

## 11 · Select the complete beam run
For a continuous beam, select the complete run before editing existing reinforcement. In this example, select both wide beam hosts and click Finish. The tool can reject a single host when its existing reinforcement belongs to a larger run. Return to selection and include every host in that run. This example uses a twelve hundred by five hundred millimetre beam section.

## 12 · Select secondary beams
Use the selector beside Secondary beams. Check the highlighted crossing beam, remove unwanted preselected elements, and click Finish. A beam used as a support belongs in the separate support selector. Do not classify the same crossing beam in both roles. In this build, the quick selection counter can remain at zero. Confirm the junction in the detailed reinforcement preview before continuing.

## 13 · Main bars for a wide beam
Set six eighteen millimetre main bars at the top and six at the bottom. Then open Edit details. Review the values for every span, because saved span settings can differ from the quick defaults. Check the numbered bar positions in the section. These positions are used when adding inner ties, so finish the longitudinal layout before assigning tie positions.

## 14 · Hanger bars and junction ties
Open Stirrup, then Secondary beams. Enable hanger bars. This example uses sixteen millimetre bars, quantity two, and a three hundred millimetre end extension. Enable the additional junction stirrups: eight millimetre diameter, five ties on each side, fifty millimetre spacing, and fifty millimetres from the secondary beam face. Toggle the options to see their effect, then check the hanger and tie geometry at the junction.

## 15 · Inner ties for wide beams
Open the Additional tab. Choose a vertical tie, diameter eight, and position two, then click Add. Repeat for position five. For an inner closed tie, choose the closed shape, start position three and end position four, then Add. Select a listed tie before using Modify or Remove. Position numbers refer to the current section layout. Recheck them whenever you change the number or arrangement of longitudinal bars.

## 16 · Stirrup shapes and hooks
Open Shapes. The main and inner stirrups have separate shape choices. Compare the closed and U-shaped options in the preview. Select the required hook arrangement; this demonstration returns to the closed layout with the one hundred and thirty-five degree hook option. Confirm the section at the support and in the span before creating reinforcement. A preview choice must match the detailing specified for your project.

## 17 · Spacing and copying settings
Return to Distribution. Use eight millimetre stirrups, one hundred millimetres in the end zones, and two hundred millimetres in the middle. Here, both end zones are set to sixteen hundred millimetres. Apply to all copies the stirrup configuration, but preserves each target span's end-zone lengths and its main-stirrup skip setting. Select the next span and check those values separately. Then create reinforcement and inspect the actual wide-beam junction in Revit.

## 18 · Enable additional layers
For additional reinforcement, first enable the required layers in Quick Setting. Here, Top additional layer two and Bottom additional layer two are enabled with two fourteen millimetre bars. Open Edit details, then Add. Top Bar or Add. Bot Bar. Select the reinforcement row before changing its fields. A layer that was not enabled in Quick Setting may not be available in the detailed layer list.

## 19 · Top reinforcement over a support
Select the top reinforcement row at the internal support. In this example, use layer T two, two fourteen millimetre bars, and a left and right ratio of zero point two five. The displayed extension is about fifteen hundred and fifty-one millimetres on each side for this fixture. Check the support index, start and end types, calculated lengths, and the preview. Add creates a row; Delete removes the selected row; Delete All clears the additional-bar list.

## 20 · Bottom reinforcement in a span
Select the B two row in Add. Bot Bar. This example uses two fourteen millimetre bars and end ratios of zero point one two five. The calculated bar length is about forty-six hundred and forty-six millimetres. Change the left ratio to zero point one five and compare the preview, then restore zero point one two five. Enter a complete valid decimal value. The recorded build can reject intermediate text while a decimal is being typed.

## 21 · Side bars in a deep beam
Open Anti bulge rebar. The beam is eight hundred millimetres deep and the minimum eligible height is seven hundred. Use fourteen millimetre side bars, eight millimetre cross ties, spacing four hundred, and anchorage one hundred millimetres. Compare one row with two rows, then return to one. Zero rows omits this reinforcement. A five hundred millimetre deep beam does not qualify with the same seven hundred millimetre threshold. Create reinforcement and inspect the deep-beam result.

## 22 · Anchorage, cover and spacers
Open Reinforcement settings. Review the anchorage factors for each support type, concrete cover, and clear distance between layers. The recorded settings show twenty-five millimetres for cover and layer clearance, and fifty millimetres as the maximum step for bent bars. In Add Setting, review spacers separately from side bars. This example has bar spacers, diameter twenty-five, at two thousand millimetres. The C-stirrup spacer is an alternative, with its own diameter and spacing.

## 23 · Small stepped beam
Select all three hosts and enable Lowered slash stepped beam. The example uses three eighteen millimetre main bars at both top and bottom, with additional layers disabled. In Geometry, select the middle span and check its elevations. The middle beam is twenty-five millimetres lower than its neighbours. Review the main-bar continuity around the support, create reinforcement, and inspect the actual joint. This run created one hundred and two rebar elements.

## 24 · Larger stepped beam
Repeat with the one hundred millimetre step fixture, keeping the same main-bar quantities. The middle span has top and bottom elevations of thirty-five hundred and twenty-nine hundred millimetres. This is larger than the recorded fifty millimetre bend-step setting. Review the separate bar ends and anchorage at the supports rather than assuming continuity from the small-step case. The run created one hundred and thirty rebar elements. Inspect both the preview and the generated joint.

## 25 · Verify and save the result
The wide-beam run created four hundred and thirty new rebar elements; the deep-beam run created two hundred and fifty. These are creation counts, not whole-model totals. The report also notes that older bars without this version's ownership marker are retained. Inspect for overlapping existing reinforcement, verify representative diameter, quantity and spacing in Revit, and save the practice model. Keep the reinforcement preview, the creation report and the actual model result as three separate checks.

## 26 · Drawing settings and a failed sheet attempt
To request a drawing, enable Create drawing sheet, enter a sheet number and name, and open the drawing template settings. Review the title block, longitudinal and cross sections, view templates, scales, dimensions and tag families. Apply validates the configuration. In this recording, missing families blocked the simple fixture. A richer model reached the sheet and creation report, but then raised an object-reference error. The sheet was not verified as a persistent result. Check Project Browser after an error; do not assume a success message proves the drawing survived.

## 27 · Apply to multiple independent beams
Multi beams selects additional hosts, each processed as an independent run. Start with the base beam, switch drawing creation off, then click Multi beams, select the extra hosts and Finish. This example uses three eighteen millimetre main bars at the top and bottom, and zoned eight millimetre stirrups at one hundred and two hundred millimetres. Create Rebars Immediately runs the batch. The recorded batch created two hundred and thirty-seven elements. Its warning says a meeting beam on another axis is treated as a free end and directs that junction to Beam Rebar Axis. Inspect that limitation before accepting the result.
