Reinforcing Bar Development and Splice Lengths per ACI 318-99
"XBRACING.xls" is a MS-Excel spreadsheet workbook for the
analysis of vertical bents with tension-only X-bracing. The workbook
contains 10 calculation worksheets, one each for bents from 1-story
through 10-stories high. The user inputs the story heights, bent
width, and lateral loads applied to each story or strut level. The
program determines all of the member (segment) forces, as well as the
horizontal and vertical reactions at the supports, and the individual
story drifts (horizontal deflections).
"Old timers" can certainly remember the days when one drew a sketch of the braced bent and traced the loads/forces down through the braced bent. Well, this does it much faster for you, plus you get a good estimate of the deflections (story drifts) as well. For preliminary designs and estimates this is still much faster than structure modeling using computer software.
All the worksheets are independent and self contained, so that you can move them from one workbook to another. All the worksheets are protected, but not with a password.
Please read the "DOC" worksheet for program details as well as assumptions and limitations.
This repository also contains "REBARS (318-05).xls" which uses ACI 318-05 Code.
