The , published by the Canadian Institute of Steel Construction (CISC) , is the definitive reference for structural engineers designing in Canada and aligning with updated code requirements. Authored by R.A. MacCrimmon, this guide serves as a practical, in-depth manual for applying limit states design to crane runway girders and supporting frames. 1. Context: What's New in the 4th Edition (2021)

Consider a new steel mill with a 50-ton, Class E crane (heavy service, 4 cycles/hour, 20 years). Using the 3rd edition (2010), an engineer might spec a W36x160 runway beam with simple bolted splices. Major Updates in the 4th Edition The ,

Industrial structures are unique because crane loads—such as vertical wheel impact, side thrust from trolley braking, and longitudinal traction—frequently dominate the entire structural design. The guide addresses these specialized needs by:

The , written by R.A. MacCrimmon and published by the Canadian Institute of Steel Construction (CISC), is the definitive technical standard for designing crane runways and industrial buildings under Canadian codes. side thrust from trolley braking

Designing structures that support moving overhead cranes requires a unique blend of structural integrity and precision. The release of the
