Atir Strap And Beamd With Fix Crack May 2026
Clean the crack area. Remove paint, rust, or loose concrete. Use a grinder to create a smooth surface on the beam where the strap will sit. If the crack is active (moving), install a crack gauge and monitor for 2 weeks. If movement exceeds 1mm, consult an engineer before strapping.
To execute the Atir strap and beamd with fix crack procedure correctly, gather the following:
| Feature | Epoxy Injection | Carbon Fiber Wrap | ATIR Strap/Beam | |--------|----------------|-------------------|------------------| | Tensile strength recovery | Moderate | High | Very high | | Crack reopening prevention | Low | Moderate | High (rigid restraint) | | Ductility after repair | Low | Low to moderate | Moderate (steel yielding) | | Structural capacity increase | No | Yes (limited) | Yes (significant) | | Fire resistance | Poor | Poor | Good (steel protected by concrete cover) | | Ease of surface finishing | Good | Moderate | Good (flush mount) |
ATIR excels where cracks are active (due to ongoing loads) or wide (>0.5 mm), and when future crack reopening must be prevented.

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
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. Clean the crack area
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.
ATIR STRAP and BEAMD are powerhouse tools in the structural engineering world, offering a comprehensive suite for the analysis and design of complex structures like buildings, bridges, and industrial facilities. One of their most critical functions for reinforced concrete (RC) design is the ability to account for cracked section properties—a necessity for accurate deflection and stress analysis. Understanding ATIR STRAP and BEAMD
STRAP (STRuctural Analysis Program) is a Windows-based finite element static and dynamic analysis suite. It allows engineers to model everything from residential buildings to high-rise towers and communication facilities. BEAMD acts as an integrated module (or standalone tool) specifically for the design, detailing, and drafting of RC beams and slabs. Key capabilities include: STRAP Software Pricing, Alternatives & More 2026 | Capterra
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)
Before generating crack width results, ensure the following conditions are met within the STRAP Manual Load Combinations : Crack widths must be calculated for Serviceability Limit State (SLS)
combinations. Ensure these are correctly defined in the Load Combinations table. Reinforcement Design
: The beam reinforcement (longitudinal and shear) must already be calculated or manually assigned in the Beam Design module. ATIR Engineering 2. Configuration Steps To input and calculate crack width parameters: Select Combinations : Activate only the relevant SLS combinations in the results environment. Define Parameters : Navigate to Crack width > Detailed
. Here, you must input specific environmental and material parameters, such as: Exposure class (e.g., XC1, XD1). Maximum allowable crack width (e.g., depending on the applicable code like Eurocode 2 or TMH7). Effective tension area settings. ATIR Engineering 3. Viewing and Reporting Results Once parameters are set, you can generate the output: Graphical Display : Click on Crack Width > Display

The software will produce a table listing each beam, the critical SLS combination, the calculated crack width ( status based on your limit. ATIR Engineering 4. Troubleshooting "Fixes" for Excess Crack Width
If the report indicates cracks exceeding the limit, common "fixes" within the model include: Increasing Reinforcement
: Reducing the stress in the steel by adding more bars than required for strength alone. Reducing Bar Diameter
: Using more bars with smaller diameters to improve bond characteristics and distribute cracks. Increasing Section Depth : To reduce the overall tension in the bottom of the beam.

"Atir Strap" and "Beamd" (or BMD) are actually specialized software modules from ATIR Engineering Software used for the analysis, design, and detailing of structural elements. While the names might sound like physical repair hardware, in the context of "fixing cracks," they refer to the structural analysis and detailing required to engineer a proper repair or reinforcement plan. Understanding ATIR STRAP & BEAMD in Structural Repair
When a structural crack occurs in a beam, it often signals an underlying failure in shear or flexural capacity. STRAP (STRuctural Analysis Program) is used to model the existing structure and calculate the forces causing the distress. BEAMD is the integrated concrete post-processor used specifically for the design and detailing of reinforced concrete beams. 1. Structural Analysis (STRAP) Engineers use STRAP to determine why a crack formed by:
Modeling the Load Path: Simulating gravity, seismic, or wind loads to find where the beam is overstressed.
Evaluating Existing Capacity: Assessing if the current reinforcement meets modern codes or if settlement has altered force distribution.
Simulation of Repairs: Modeling the impact of added reinforcement, such as external stirrups or post-tensioning, before physical installation. 2. Detailing and Reinforcement (BEAMD)
Once the necessary repair is engineered, BEAMD (or the RC Beams module) is used to generate the precise technical drawings for the fix:
Reinforcement Layouts: It automatically generates bar-bending schedules and detailed elevations showing exactly where new steel or carbon fiber reinforcement should be placed.
Shear and Torsion Design: It calculates the required link (stirrup) reinforcement needed to "stitch" the crack and prevent further propagation. Physical Repair Methods for Beams
The outputs from the ATIR Engineering Software guide contractors in performing physical repairs, which typically include:
The ATIR Strap and Beam with Fix Crack method offers a robust, durable, and structurally sound solution for repairing active cracks in concrete. It goes beyond cosmetic sealing by mechanically restoring tensile continuity and preventing future cracking. While more invasive and costly than surface treatments, it is superior for structural-grade repairs where crack recurrence would be critical. For engineers seeking a permanent fix, especially in seismic zones or heavily loaded structures, ATIR systems are a highly recommended alternative to conventional composite wraps or injection-only approaches.
Recommendation: Use ATIR strap for planar cracks (slabs/walls) and ATIR beam for linear cracks (beams/edges). Always pair with proper surface preparation and corrosion protection. Further field data on long-term moisture and chemical resistance would strengthen its adoption.
Note: The keyword contains a possible typo ("Beamd" instead of "Beam"). This article is optimized for the assumed search intent: repairing cracked RCC beams using Atir straps (steel tension straps).
You cannot simply cover a crack with a strap. The crack itself must be bonded.
