) according to building codes (e.g., reducing beam stiffness to 0.35Ig0.35 cap I sub g and columns to 0.70Ig0.70 cap I sub g per ACI 318). Serviceability Limit State (SLS) Checks

Use the Structural Inspection tab to view deformation and shell element results (like moment diagrams M₁₁, M₂₂) 1.2.3.

Imagine a high-rise building modeled in ideCAD. At first glance, everything is perfect: reinforcement ratios are optimal, column dimensions are code-compliant, deflection limits are satisfied. But when you run a nonlinear analysis—perhaps a pushover or a time-history analysis under seismic loading—the software reveals something unexpected: fine, hairline cracks forming at the beam-column joints on the 7th floor. idecad structural crack

If the steel ratio is already nearing the maximum allowed limit ( ρmaxrho sub m a x end-sub

ideCAD automatically calculates immediate and long-term deflections, factoring in concrete creep and shrinkage. By checking the reports against code limits (such as ACI 318 or Eurocode 2 limits of

By mastering the balance between raw cross-sectional geometry, meticulous reinforcement spacing, and the correct application of cracked stiffness modifiers within , you can deliver safe, economic, and completely code-compliant structural designs. ) according to building codes (e

Following the automatic code checks, ideCAD presents a full summary of the analysis, including detailed design results for concrete elements, crack control results, and reinforcement details.

Re-run the structural analysis. ideCAD will utilize the reduced moment of inertia to generate updated internal force diagrams, deformation shapes, and structural period values. 4. Investigating Cracks Using ideCAD Analysis Output

[ w_k = s_r,max \cdot (\varepsilon_sm - \varepsilon_cm) ] At first glance, everything is perfect: reinforcement ratios

Volume changes during concrete curing or extreme temperature swings without adequate expansion joints.

Large rebar diameters spaced far apart lead to wide, concentrated cracks.

Before delving into ideCAD's computational methods, it is essential to understand why crack control is a fundamental aspect of modern structural design.

Structural cracking is an inherent characteristic of reinforced concrete behavior. While concrete exhibits high compressive strength, its tensile capacity is limited, making cracking an expected phenomenon under service loads. The critical challenge for structural engineers lies not in preventing cracks entirely but in controlling their width to ensure durability, serviceability, and aesthetic acceptability. , an integrated Building Information Modeling (BIM) software, provides advanced capabilities for analyzing, calculating, and controlling cracks, ensuring designs comply with major international codes such as TBDY 2018 (Turkey), TS 500, ACI 318-19, and Eurocode 2.

Torsional cracks occur when a structural member is subjected to twisting moments, common in edge beams supporting cantilevered slabs. These cracks form a continuous spiral pattern around the perimeter of the element. 4. Excessive Deflection and Overloading
