As part of a continuing effort to provide current and practical information for engineers, architects, designers, educators, fabricators and others interested in the use of steel in construction, the CISC recently launched a new series of concise steel design modules (referred to as parts). Each part of the Steel Design Series (SDS) focuses on a steel design topic. The SDS covers materials that are in popular demand or serve to promote the use of steel structures. The Solutions Centre aims to develop five parts per year.

SDS Part 1 “ULC and cUL Spray-Applied Fire Rated Steel Designs” published in May 2017 is currently available as a free download from the new CISC website: It provides a summary of fire-rated designs consisting of steel members protected with spray-applied fire resistive material (SFRM). These rated designs are generally valid for use in commercial, institutional, light industrial and residential buildings in Canada, and are free from ‘load restriction’. They include selected designs listed in the Underwriter Laboratories of Canada (ULC) Directory and those listed in the Underwriter Laboratories Inc. (UL) Directory as cUL designs. SDS Part 1 focuses on practical and economical SFRM protected designs for columns, floor and roof assemblies.

Designs that feature intumescent coatings are also available and the topic will be covered in another Part in the CISC Steel Design Series. Other Parts that will soon be published and made available on CISC website include:

  • Design of bolt groups subjected to eccentric and inclined loads
  • Design of high-strength steel columns
  • Design of composite beams and
  • Design of weld groups subjected to eccentric and inclined loads.
