The validation documents / examples within this section are used to validate the accuracy of the design performed of Columns, Beams, Shear-walls, Isolated Foundations, Pile-caps.

Below is short description of the design philosophy considered in RCDC:

RCDC is a RCC design software that supports designing of various elements of a RC structure like:

Column and Shear Wall Design
Beam Design
Isolated Footings (Pad, Sloped and Step) Design
Pile Cap with Pile arrangements of 1 pile to 6 piles can be Designed.
Slab (Regular conventional slabs) Design.
Water Tank Structure Design

Short description on what is covered in the design part of each element and the validation along with code reference is provided in the validation documents available as per below list.

Column and Shear Walls Design Specifics:
- Story Sway/Non-sway condition is determined and further used for the effective length factor calculation.
- Minimum Eccentricity check is performed.
- Slenderness check is performed and for slender column the magnified slenderness moment is also calculated based upon code guidelines.
- Biaxial bending design by plotting the 3D Interaction curve is performed.
- Shear check is performed and for ductile columns the additional shear from beams is also considered while finalizing the Final Shear Force.
- Ductile Links design as per code guideline is performed.
- Crack-width check as per user requirement and settings is performed.
- Joint check for Ductile columns is performed.
Beam Design Specifics:
- Beams are designed and detailed based on its type whether Simply supported or Continuous or Cantilever.
- Flexure + Torsion design and Shear + Torsion design is performed zone wise in left mid and right zones.
- Skin reinforcement or the Side face reinforcement is provided depending upon different criteria mentioned in different design codes.
- Crack-width check as per user requirement and settings is performed.
Footing Design Specifics:
- Type of footing – Pad, Step, Sloped or On-raft can be assigned and further the Footings are sized by performing the Maximum and Minimum pressure check.
- The sizing is checked for the Stability checks like Buoyancy, Sliding and Overturning.
- Depending upon the Design method selected (Average Pressure / Maximum Pressure / Factored SBC), Flexure design is performed, and reinforcement configuration is finalized.
- One way shear as well as Punching shear check is performed, and the required depth of the footing is finalized. If there is restriction on the maximum depth only then RCDC will go ahead and provide the Stirrups if required.
- The load transfer check is performed and wherever the footing size if insufficient to transfer the load, provision is made to provide the required Dowel bars.

Pile cap Design Specifics:
- RCDC will determine the Pile configuration as per the Pile capacities entered by user.
- The Pile cap is designed considering various checks like Pile overloading check, Pile group overloading check considering user settings made pre-design.
- Flexure design is performed for the Pile cap using the Beam-theory.
- One-way shear check is performed, and depth is finalized for shear requirement.
Slab Design Specifics:
- Slabs in RCDC are detected to be enclosed between the polygon formed by Beam frame.
- Dead load and live load intensities needs to be provided in RCDC for performing the design.
- The Type of Slab and the Type of Span is determined as per Design code Guidelines.
- Slab is further designed for flexure and checked for shear and deflection.
Water Tank Design Specifics:
- For this module in RCDC, the Tank Walls and the Tank Slabs gets designed and also if any miscellaneous structure with a beam column geometry can be designed.
- Tank Walls and the Tank Slabs are designed for Flexure and Shear and further the check for Crack width and Drying and Thermal Shrinkage can be selected to be performed.
- Multiple zones are created to handle Design as well as Detailing of the Vertical and Horizontal reinforcement in the Tank Walls.
- The Vertical reinforcement is Curtailed also depending upon the Wall geometry and Reinforcement requirement along the height of the Wall.
