This thread will track of the version history of the following download:
REBARS (318-08).xls
"REBARS (318-08).xls" - This workbook is for the calculation of reinforcing bar development and splice lengths per the ACI 318-08 Code.
This workbook is the same in form and function as the workbook for the previous ACI 318-05 Code. The changes from the ACI 318-05 Code to the ACI 318-08 Code were in general very minor, with the resulting basic development lengths determined from Chapter 12 being basically the same. One note, the factor for lightweight concrete, "lambda", which was previously 1.3 and in the numerator of the basic development length equations in the '05 Code, is 0.75 and located in the denominator (1/0.75 = 1.333) in the '08 Code......different presentation, but basically the same results.
