Frequently Asked Questions (and Answers!)

Q. What are the functions of SCADDS/RC-Footing Designer?

A. SCADDS/RC-Footing Designer is meant for Limit State design of masonry wall or concrete wall footings, Isolated Rectangular or Circular Footings and Combined Rectangular or Trapezoidal Footings subjected to Axial Load and bending as per IS:456. You also have a choice of providing a pedestal for Isolated or Combined Footings. Moreover, the footing section can be flat or sloped in case of Wall footings or Isolated footings.

Q. If a pedestal is assumed, will the design be done automatically?

A. Yes. If you assume a pedestal and specify the pedestal projection from the column face, SCADDS/RC-Footing Designer will design the dowel bars and also check for bearing stresses as per IS:456. Moreover, the depth of pedestal will also be optimized in order to save the volume of concrete for the whole footing.

Q. Is shear design for stirrups included in SCADDS/RC-Footing Designer?

A. No. It is not a common practice to provide stirrups in footings. But SCADDS/RC-Footing Designer carries out detailed shear calculations for one-way shear and punching shear.

Q. Is the design interactive in nature?

A. Yes. In fact, you can choose from four methods for proportioning the length and width of the footing. During the solution phase, you will be prompted to provide your own values for the length and width against the required values shown.

Q. Will SCADDS/RC-Footing Designer arrive at a safe depth automatically?

A. Yes! If the given thickness or depth of footing is inadequate, the section will be revised automatically in order to give you a section which is safe in flexure and shear.

Q. Does it design eccentric footings or "shoe" footings?

A. No. The present version does not design footings which have eccentric columns. However, you can design footings with combined axial load and uniaxial or biaxial bending maintaining a symmetrical geometry. Please note that the next upgrade will include design of isolated footings which have unsymmetrical geometry.

Q. What is the input required to be given for designing a footing?

A. The type and shape of the footing, dimensions, Concrete Grade (either standard or user-designed mix), steel grades & rod sizes and the working forces and moments.

Q. What is the output produced by SCADDS/RC-Footing Designer?

A. The output for a design problem contains detailed reports on design for flexure, design for pedestal (if provided), check for one-way shear, check for punching shear and design for bond. (Top)
