  1. Can RCDC design Curved beams? Will it convert the curved beam composed of many parts to a single physical beam?
  2. Can RCDC provide bottom bar without curtailment in single span?
  3. Can number of bars for the given width of beam be edited?
  4. Can RCDC provide the detailing of beam with lowest diameter throughout the length and balance area of steel with higher diameter in other layer?
  5. Does RCDC allow to provide only 2 bars for top reinforcement?
  6. What is the purpose of mirror & straight option in group/ungroup tab?
  7. Why specifically only 13 stations (for beams) can be imported from E-tabs to RCDC?
  8. Side face reinforcement calculation in RCDC
  9. Please give clarification of failure type for beam element. Failure type – Shear –Tc max
  10. Even after opting best fit for top reinforcement, why does RCDC provides higher reinforcement (as per minimum Pt) at top at mid-span?
  11. Why default 0.2% is provided for nominal steel in RCDC? Does it have any reference?
  12. Is there any option to disregard the contribution of concrete in resisting shear for beam when IS 13920-2016 is used?
  13. When IS 13920 is selected, does RCDC consider required rebar or provided rebar to calculate capacity (plastic) shear force (or moment capacity) for beam?
  14. Does RCDC calculates moment capacity for sway shear calculations as per rectangular section or flanged section for beam?
  15. If Beam is designed for axial plus biaxial forces, ideally if axial force in beam is less than the permissible value of IS 13920 code, the member should be designed as beam only both for strength and crack width and check as per columns not be applicable
  16. Ignoring concrete capacity in beam design as per clause 6.3.4 of IS 13920-2016
  17. In Beam design output of stirrups, what is 2L-T8 (H)?
  18. If the Beams exists at support level of the structure, can it be designed in STAAD Advanced Concrete Design (RCDC)?
  19. How to make beams pass if failed due to shear stress exceeds maximum permissible shear stress (TauC)?
  20. Beams can be designed in groups if the Beam arrangement is similar at all Floors.
  21. Sway Shear Calculation for Ductile Beam Design
  22. How to calculate reinforcement of beam at face of column in RCDC?
  23. Why RCDC is giving more reinforcement at bottom near supports as curtailed bars?
  24. Which option can be used to save the reinforcement for long span beams in RCDC?
  25. In RCDC Detailing option is available in Design Settings.
  26. Customized curtailment provision in RCDC?
  27. In BBS for ductile beams, there should be no lap splice within the joint and within 2D from the face of the column. (ACI 318M – 14 cl. 18.6.3.3)
  28. Serviceability check for allowable deflections as per ACI 318M-14
  29. RCDC is considering 'Zero" bending moment at left and right support despite there being some Bending moment at the support.
  30. How the effective depth is calculated in beam design and what is the impact of “maximum Aggregate 2 Size” on effective depth?
  31. Why is RCDC taking wind load shears to do ductile detailing for earthquake loads?
  32. Does STAAD advanced concrete design (RCDC) consider the contributing effects of the slab flanges in RC beam design?
  33. Clarification regarding the curtailment of 100% top reinforcement.
  34. What is the purpose of the Ignore Torsion feature available in RCDC Design setting?
  35. RCDC is providing steel for beams in several layers of 12mm dia. for some Beams
  36. Asv required for is greater than Asv provided.
  37. Detailing of beams with different depths in RCDC
  38. Query related to Force matching with ETABS ACCDB
  39. Beam ductile link calculation as per IS 13920-2016 cl 6.3.5 (b)
  40. Beam Design for Biaxial Moment
  41. Beam design with axial force and Biaxial Moment - Side face reinforcement for Column detailing
