Frequently Asked Questions (and Answers!)

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

A. SCADDS/RCSlab Designer is meant for Limit State Design of One-way or Two-way or Cantilever Rectangular Slabs and Circular slabs for various common support conditions as per IS:456.

Q. Will SCADDS/RC-Slab Designer arrive at a safe depth for the slab automatically?

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

Q. Will it also design Torsional reinforcement, in case of Two way slabs?

A. Yes. SCADDS/RC-Slab Designer will design the Torsional reinforcement automatically for Two way slabs based on the support conditions.

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

A. The effective shorter span and longer span of the slab (or the effective diameter for circular slab), initial dimensions for the section, Concrete Grade (either standard or user-designed mix), steel grades & rod sizes, and the working Loads. The entire input can be done within a matter of 3 to 4 minutes, thanks to ultra user-friendly interface and data input dialog boxes.

Q. Should I remember the Live Load for each floor category and each building category?

A. Absolutely Not! SCADDS/RC-Slab Designer has a built-in database having the various Live Load intensities for different categories of floors and buildings as per Is:8751987 (Part 2). These categories vary from simple residential buildings to industrial buildings and storage structures.

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

A. The output for a design problem contains detailed reports on design for flexure, check for shear, design for bond, design for torsional reinforcement (if applicable) and check for deflection. (Top)
