Spreadsheet: Development Lengths and Splice Lengths for Steel Reinforcement in Tension and Compression as per ACI 318-05

"REBARS" is a spreadsheet program written in MS-Excel for the purpose of determining reinforcing bar development and splice lengths. 
"REBARS" is a spreadsheet program written in MS-Excel for the purpose of determining reinforcing bar development and splice lengths.
Specifically, the development lengths and splice lengths for straight bars in tension as well as compression are determined. Also, the development length for standard hook bars is determined. The provisions for development and splice lengths are included for high seismic risk applications per ACI 318-05, Chapter 21. There is also a worksheet which contains reinforcing bar data tables. This version is based on the ACI 318-05 Code.

Program Assumptions and Limitations:

1. This program follows the procedures and guidelines of the ACI 318-05 Building Code, Chapters 12 and 21.
2. The "Calc Development" worksheet, for a given reinforcing bar size, determines the straight development and  splice lengths for a "top" bar and an "other" bar in tension, the straight development and splice lengths for the  bar in compression, and the tension development length of the bar as a standard hook, all at one time.  A complete table of reinforcing bar development and splice lengths is also created for #3 through #18 bars.
3. The "Rebar Data" worksheet contains tables of reinforcing bar data which include various bar properties,  reinforcing bar areas based on spacing, tension development and splice lengths for straight bars, tension  development lengths for 90 degree standard hooks, tension lap splice criteria, compression development  and splice lengths for straight bars, maximum spacing for column ties, and various plain welded wire fabric  properties.
4. This program contains numerous “comment boxes” which contain a wide variety of information including  explanations of input or output items, equations used, data tables, etc. (Note: presence of a “comment box”  is denoted by a “red triangle” in the upper right-hand corner of a cell. Merely move the mouse pointer to the  desired cell to view the contents of that particular "comment box".)
