To properly analyze a cracked beam or slab, you must create at least three separate load combinations in the Results module:
The engineer models the structural frame or slab system using line elements or shell elements. Load cases must be explicitly split into separate and Live service components within the menu:
Create a shear spring link between the beam nodes and the strap nodes. Atir Strap And Beamd With Fix Crack
A fundamental engineering principle is that treating the symptom (the crack) without addressing the cause is a recipe for failure. A repair plan must be designed to not only fix the existing damage but also to prevent it from recurring. Common root causes include:
The Atir Strap and Beam system offers numerous benefits, including: To properly analyze a cracked beam or slab,
Use post-repair UPV testing data to estimate the actual density and continuity of the epoxy fill, translating those wave speeds into an accurate Modulus of Elasticity ( ) value for your STRAP input.
: Ensure only Serviceability Limit State (SLS) load combinations are active before performing the check. A repair plan must be designed to not
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.
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.
