Modern seismic design codes require engineers to analyze structures using . Because concrete cracks under service loads and earthquake actions, using uncracked (gross) section properties underpredicts structural displacement (drift) and incorrectly distributes internal forces.
Over-restraint causes internal tensile stresses that manifest as cracks.
The following table shows the multipliers automatically applied by ideCAD: idecad structural crack
Real-world concrete cracking due to bending, shear, torsion, or shrinkage, which the engineer must prevent or control using the software's design modules.
tab allows you to quickly identify elements that fail crack or reinforcement checks. Elements with insufficiencies are flagged in for immediate review. How to Access Crack Results To review crack-related data in ideCAD Structural Analysis + Design (F9) to generate structural results. Navigate to the Ribbon Menu Structural Inspection Concrete Design Modern seismic design codes require engineers to analyze
). Instead, . Example: Replace 2 20 bars with 4
Using the 'Analysis Plus Design' command, ideCAD conducts comprehensive vertical load analysis and modal analysis to understand natural vibration modes. This helps identify resonance issues that can lead to excessive deflection and subsequent cracking. C. Pushover Analysis How to Access Crack Results To review crack-related
: Alternatively, in ideCAD's finite element stress contours, high tensile stress zones are visually represented. If these exceed allowable thresholds, the software flags them as areas prone to severe structural cracking, requiring design intervention. Why Cracked Section Analysis Matters
"We need to act fast," warned Dr. Rachel Kim, a leading structural engineer on the Idecad project. "If that crack continues to spread, it could compromise the entire complex, putting thousands of lives at risk."
