"REBARS" --- REINFORCING BAR DEVELOPMENT AND SPLICE LENGTHS

Program Descripio!

"REBARS" is a spreadsheet program written in MS-Excel for the purpose of determining reinforcing bar

development and splice lengths. Specificall! the development lengths and splice lengths for straight bars in

tension as well as compression are determined. Also! the development length for standard hoo bars is

determined. #he provisions for development and splice lengths are included for high seismic ris applications

per A$% &'(M-)*! $hapter +'. #here is also a worsheet which contains reinforcing bar data tables.

T#is METRIC $ersio! is %ase& o! #e ACI '()M-*+ Co&e,

#his program is a worboo consisting of five ,* worsheets! described as follows

all at one time. A complete table of reinforcing bar development and splice lengths is also created.

#his worsheet can be utili1ed for cases where the design concrete code used is A$% &'(-)*! but where the

reinforcing bars to be provided are European ,British Standard bar si1es! not 7.S. bar si1es.

designations represent the exact bar diameter expressed in millimeters.

3. #he "Rebar /ata ,Soft Metric" worsheet contains two tables of reinforcing bar data which include various

bar properties as well as reinforcing bar areas based on spacing using units of mm8+9m.

6. #he "Rebar /ata ,Euro Metric" worsheet contains two tables of reinforcing bar data which include various

bar properties as well as reinforcing bar areas based on spacing using units of mm8+9m.(. #his program contains numerous :comment boxes; which contain a wide variet of information including
