“FLRPLATE” — STEEL CHECKERED FLOOR PLATE DESIGN

“FLRPLATE” — STEEL CHECKERED FLOOR PLATE DESIGN

Program Description:

“FLRPLATE” is a spreadsheet program written in MS-Excel for the purpose of designing steel checkered floor
plate subjected to uniformly distributed loading.

This program is a workbook consisting of two (2) worksheets, described as follows:

Program Assumptions and Limitations:

1. This program utilizes the formulas given in “Design of Welded Structures” by Omer W. Blodgett (James F.
   Lincoln Arc Welding Foundation) in Table 1 on page 6.5-4. The formulas therein were taken from “Formulas
   for Stress and Strain”, by Raymond J. Roark, for rectangular flat plates subjected to uniform pressure.
   These same formulas are found in “Design of Weldments” by Omer W. Blodgett (James F. Lincoln Arc
   Welding Foundation) in Table 1 on page 4.6-4 as well.
2. This program follows the procedures and guidelines of the AISC 9th Edition Allowable Stress (ASD) Manual,
   (Fourth Impression 9/00), and the “Floor Plate Bending Capacity” Table found on page 2-145 is replicated off
   of the main calculation worksheet at the right side of the screen. Also, at the right side of the screen, there
   are two (2) additional allowable uniform loading tables, one based on flexural strength and the other based
   on deflection criteria. Both of these tables consider the user input value of the plate yield stress, ‘Fy’.
3. If the user desires to simulate true one-way span action for the plate analysis and design, then a value of the
   plate long span, ‘L’, which is input should be at least 8 times the value of the plate short span, ‘S’.
