Steel Deck Design for Concentrated and Non-Uniform Loading

December 9, 2020 @ 12:30 pm – 2:00 pm

Speaker: Mike Antici
Nucor / Steel Deck Institute


Steel floor and roof deck manufacturers publish load tables for uniform loads, but what if the loads that are on your project are not uniform? Designers frequently face concentrated loads caused by rack systems, forklifts, scissor lifts, mechanical equipment, RTUs, and other dead, live, or construction loads.

This SE University session will expand upon current ANSI-SDI and ACI specifications for analysis of multiple concentrated or unbalanced load groups on steel roof and floor decks. During the session, Mike Antici of Nucor / SDI will present design methodology for non-uniform loading with examples, discuss rational analysis, and review existing design handbooks.


Learning Objectives:

  • Recognize load distribution, and develop “simple” load diagrams.
  • Understand the limit states for slab design under concentrated loads.
  • Review current and new SDI design approaches for concentrated loads.
  • Understand example problems for design with concentrated loads.


Handout and registration emails for this session will be sent to SE University companies on Friday, December 4th.
