Atir Strap And Beamd With Fix Crack Guide
Before we discuss the fix, we must decode the keyword. In structural engineering slang, "Atir" may refer to:
For the purpose of this guide, we define the Atir strap as a pre-galvanized or stainless steel flat bar with pre-punched holes, designed to resist tension forces. When a beam cracks, it loses its ability to handle tension on one side. The strap acts as an external tendon, carrying the tension load across the crack.
With proper surface preparation and corrosion protection, >25 years.
ATIR STRAP and BeamD provide powerful automated workflows for analyzing cracked concrete sections.
In structural engineering, actual concrete deflections and stress distributions are much greater than linear elastic calculations suggest. This is due to cracking, reinforcement ratios, and time-dependent factors like creep and shrinkage.
This guide outlines how to calculate crack widths, account for cracked sections in your analysis, and use the BeamD module to detail your repairs according to international codes like Eurocode 2 or ACI 318. 🛠️ Phase 1: Analyzing the Cracked Section in STRAP
Before jumping straight into reinforcement, you must calculate the reduced stiffness of the cracked concrete to understand the true behavior of the structure.
Set Up Load CombinationsTo properly analyze a cracked beam or slab, you must create at least three separate load combinations in the Results module:
Ultimate Loads (Total): To calculate the required reinforcement. Service Loads (Total): To calculate immediate deflection ( ) taking initial cracking into account.
Service Loads (Sustained): To calculate long-term deflections caused by creep. Calculate the Effective Moment of Inertia ( Iecap I sub e
)STRAP utilizes an empirical approach (like the Branson method) to solve for a reduced stiffness value based on the ratio of the actual service moment ( ) to the cracking moment ( Mcrcap M sub c r end-sub
Navigate to the side menu and select Cracked Section & Long Term Deflections.
Input the specific code parameters (e.g., Eurocode 2 or ACI 318) and specify your material properties.
Click Solve. STRAP will recalculate the model using the reduced stiffness of the cracked elements. Check Crack Width Limits
Under the concrete design options, calculate the theoretical crack widths.
Ensure that the computed crack widths do not exceed code-specified limits (typically for standard exposure). 🏗️ Phase 2: Designing the Fix with BeamD Atir Strap And Beamd With Fix Crack
Once STRAP has completed the complex Finite Element (FE) analysis, you can export the isolated cracked beam into BeamD—ATIR's specialized 2D continuous beam design and detailing module. Automatic Beam Definition
If not already done, you can use the automatic search feature. BeamD will automatically define spans and locate support widths by searching for perpendicular elements.
Adjusting the Reinforcement to "Fix" the CrackTo safely address areas experiencing heavy cracking, you must manually adjust or optimize the steel parameters:
Increase Tension Steel: Go to the reinforcement editing menu and increase the number or diameter of the bottom/top bars at the high-moment locations indicated by your analysis.
Reduce Bar Spacing: Controlling crack widths is heavily reliant on bar spacing. Smaller diameter bars spaced closer together control cracking much better than a few large diameter bars.
Side-Face Reinforcement: If your beam has a total depth exceeding
, ensure you add skin reinforcement along the vertical faces to control web cracking. Generating Output for the Field
Once the software confirms that the cracks are within safe limits and your flexural/shear capacities are met, use BeamD to produce the final outputs.
Generate an automated Bar Bending Schedule (BBS) and a detailed reinforcement sketch. 📌 Anchor Key Takeaway
⚠️ Always rely on engineering judgment. The software calculates reduced stiffness using empirical formulas. A program's calculated crack width is an estimation, and real-world factors like localized concrete honeycombing or shrinkage should always be reviewed on-site by a licensed structural engineer.

🏗️ Scenario B: You are solving a structural engineering problem
If you are an engineer using these programs legitimately and are looking for guidance on how to perform a Cracked Section Analysis or assign fixed connections for beams: 1. Concrete Crack Width & Deflection in STRAP
Crack Width Module: STRAP features dedicated modules to calculate crack widths according to regional standards like Eurocode 2 (EC2) or BS8007.
Effective Moment of Inertia: To calculate realistic long-term deflections in cracked concrete, use the program's automated routine to reduce stiffnesses based on actual reinforcement calculations rather than relying on gross uncracked section properties. 2. Beam Detailing in BEAMD
Integration: BEAMD is specifically designed to take the analysis results from STRAP and convert them into full 2D continuous beam reinforcement detailing, drafting, and scheduling.
Fixed vs. Pinned: If you need to "fix" a crack or stress issue by changing the structural behavior, ensure that the boundary conditions and beam-to-column joint releases are accurately mirrored between the main STRAP FEM model and the exported BEAMD file. To help you further, please let me know:

In Atir STRAP and BEAMD, analyzing and managing "cracks" typically refers to the crack width calculation and structural analysis of reinforced concrete members according to design codes. Crack Width Analysis in STRAP
STRAP computes crack widths specifically for reinforced concrete elements like plate elements (slabs, pile caps, etc.) to ensure they meet serviceability requirements (e.g., not exceeding 0.2mm according to standards like TMH7).
Activate SLS Combinations: Ensure only Serviceability Limit State (SLS) load combinations are active before performing the check.
Input Parameters: Navigate to the Crack Width menu and select Detailed to input required parameters, such as exposure conditions and specific code requirements.
View Results: Click on Crack Width > Display to visualize the calculated widths across the model. For the purpose of this guide, we define
Element Modeling: Note that for complex structures like bridge decks, a separate plate element model may be required for accurate crack width computation. Beam Design and Detailing with BEAMD
The BEAMD module integrates with STRAP to design and detail reinforced concrete beams according to national codes.
Automatic Definition: The program can automatically define beam spans and support widths by searching for elements perpendicular to the height axis.
Manual Refinement: Users can manually define beams by clicking nodes to set start and end points, typically from left to right to maintain local axis consistency.
Property Assignment: Beams are assigned sections (e.g., from steel tables or custom RC sections) and materials, which can be verified by displaying the section name in the model. Installation and Troubleshooting

Are you analyzing serviceability cracks in a concrete design or looking for assistance with software installation errors? RC Beams - Atir Engineering Software Development
In ATIR STRAP, managing reinforced concrete beams and addressing crack control is a core part of the design and detailing workflow. The software uses a modular approach, where the main STRAP finite element analysis results are passed to the RC Beams (often referred to in detailing contexts as BEAMD) post-processor to finalize reinforcement and check for serviceability requirements like crack widths. RC Beam Design and Crack Control Workflow
The software automates much of the process but allows for detailed manual overrides for compliance with international codes like ACI 318 or Eurocode 2. STRAP 2018 - RC Beams (Design & Detail)
To fix a crack with a strap, you must diagnose why the beam cracked. Beams fail in three primary ways:
The "Atir strap and beamd with fix crack" method works best for Flexural and Shear cracks, provided the crack width is less than 1/8-inch (3mm) for passive repair.
| Mistake | Consequence | Solution | |---------|-------------|----------| | Drilling into rebar | Severed tension steel, worse than original crack | Use rebar locator before drilling | | No crack injection | Internal void remains, corrosion continues | Inject epoxy before strapping | | Overtightening bolts | Concrete spalling around anchor | Use torque wrench + embed plate if needed | | Using untreated mild steel | Rust expansion re-cracks beam within months | Use galvanized or epoxy-coated straps | | Single strap for shear crack | Insufficient resistance – diagonal failure repeats | Apply crisscross straps (X-pattern) |
The term "Strap and Beam" refers to a method of creating hidden reinforcement beams within the existing masonry. It transforms a fragile wall into a reinforced composite panel.
