is its specialized module for reinforced concrete beam design and detailing . Analyzing a "Fixed Crack" within this environment typically refers to performing a Cracked Section Analysis
) running through the reinforcement during daily service loads, directly reducing crack width equations.
The Atir Strap and Beam system has been successfully applied in various construction projects, including: Atir Strap And Beamd With Fix Crack
) instead of just the gross section. It uses an empirical "effective" approach (such as the Branson equation in ACI 318 or Eurocode 2) to determine reduced stiffness based on the ratio of the actual moment to the cracking moment.
Yes, unless covered by false ceiling or plaster. It can be painted to match surroundings. is its specialized module for reinforced concrete beam
: BEAMD is an integrated module specifically for RC beam design and detailing. It handles the transition from 2D analysis to full reinforcement scheduling, ensuring that the designed rebar meets code requirements to control cracking. Core Software Components
ATIR STRAP (which stands for uctural A nalysis P rogram) is a sophisticated software suite developed by ATIR Engineering Software Development Ltd. Founded in 1983, the company's motto, “Simplicity is a prerequisite for reliability,” underscores its approach to creating powerful yet user-friendly engineering tools. It uses an empirical "effective" approach (such as
The beam exhibits full uncracked structural stiffness ( EIgrosscap E cap I sub g r o s s end-sub
Before any physical repair can begin, a thorough assessment and analysis are required. This is where software like ATIR STRAP and BEAMD becomes invaluable. The process begins with:
This makes the technique superior to mere grouting for structural cracks.
| Crack Width | Severity | Atir Strap Suitability | |-------------|----------|------------------------| | < 0.3 mm | Cosmetic | Not required | | 0.3 mm – 1.0 mm | Minor | Optional (monitor first) | | 1.0 mm – 3.0 mm | Moderate | Recommended | | > 3.0 mm | Severe | Mandatory + grouting |
