Sponsored by New Millennium Building Systems
Presented by Alex Therien, Market Development Manager

Learning Objectives:

  1. Name the three long-span composite floor systems and describe their distinguishing characteristics.
  2. Specify the best system for a project based on an assessment of that project’s key design criteria.
  3. Identify the main resources used to guide system selection, including engineering standards, design guidelines, and manufacturers’ tables.
  4. Explain why early collaboration with suppliers is key to the system selection process and how it impacts a project’s construction efficiency.

This course outlines the attributes, functions, benefits, limits, and acoustic qualities of composite deck slabs. It reviews the three primary types of composite systems that represent the full range of long-span composite floor systems and examines the criteria for their selection, design, and engineering. In addition, it provides a comprehensive range of industry standards and resources that a designer could consult to ensure, at a minimum, compliance with all building regulations and industry standards.
