ULS design of reinforced concrete, AS, ACI and European codes
Posted on December 21, 2010 by dougaj4
The previous post in this series compared the results of current and previous Australian Standards, and the ACI 318 code, for the ultimate bending capacity of a rectangular reinforced concrete section, subject to combined bending and axial load. I have now extended this analysis to include three European codes: the current Eurocode 2, and the recently superseded British Standard codes: BS 5400 (bridges) and BS 8110 (buildings).
The spreadsheet used in this analysis contains user defined functions (UDFs) that will carry out the section analysis for any rectangular section with 1 or 2 layers of reinforcement, for the following codes:
1.AS3600-2010, rectangular stress block (default)
2.AS5100, rectangular stress block
3.Eurocode 2, parabolic stress block
4.BS 5400, rectangular stress block
5.BS 8110, rectangular stress block
6.Not yet implemented
7.ACI 318, rectangular stress block
8.AS3600-2001, rectangular stress block
9.AS3600-Parabolic1; parabolic parameters to EC 2
10.AS3600-Parabolic2; parabolic stress block converted to equivalent rectangular block
