is a specialized module for the 2D design and detailing of reinforced concrete beams.
The specialized 2D/3D continuous beam analysis, post-processing, and rebar detailing module. It takes the geometric data and raw finite element forces calculated by STRAP to generate physical reinforcement patterns and exact bar bending schedules. The Engineering Challenge: Cracked vs. Gross Sections
Closed loops of reinforcement bar (rebar) wrapped around the main longitudinal bars. They resist shear forces and prevent diagonal tension cracking. Identifying the Types of Cracks
: Concrete beams under combination forces lose up to 80% of their torsional stiffness once cracked. This drop significantly alters how moments redistribute throughout continuous spatial frames. 2. Setting Up Cracked Parameters in ATIR STRAP atir strap and beamd with crack new
Adding steel cables to tighten the structure. ⚠️ Warning Signs Cracks wider than 0.3mm . Exposed or rusting rebar. Spalling (concrete falling off in chunks).
Straps can be wrapped passively around a beam to catch loads when shifting occurs, or actively post-tensioned to squeeze the crack shut immediately. 2. Structural Beamed Support
Once repaired, implement these monitoring and design improvements: is a specialized module for the 2D design
The software calculates the cracking moment ( Mcrcap M sub c r end-sub ) for each element. If the applied moment ( Mcrcap M sub c r end-sub , the program reduces the stiffness accordingly.
: Poor site drainage softens the ground directly under the foundation elements. 2. Concrete Curing Issues
When building a new home or addition, consider the following best practices to minimize the risk of cracks in your ATIR strap and beam: The Engineering Challenge: Cracked vs
Under the General Tab of the Concrete Post-Processor, verify the . This allows the software to properly separate horizontal beams from vertical columns.
While STRAP provides the overall structural analysis, is the specialized tool dedicated to reinforced concrete beam design, detailing, drafting, and scheduling. The software description calls it “the complete and totally integrated solution for RC beam design” that “transforms a tedious and error‑prone task into a fast, efficient and enjoyable interactive design experience” .
Place a thin glass slide or a plaster dot across the crack. Check after 7 days. If broken or offset → requiring structural intervention, not just cosmetic fill.
Concrete is exceptionally strong under compression but inherently weak under tension. When a concrete beam experiences loads beyond its design capacity, environmental stressors, or seismic activity, it develops cracks.
