Concrete Stress Blocks

Back in 2010 and 2011 posts here looked at a comparison of alternative stress blocks in the then new AS 3600, and a procedure for calculating parameters for a rectangular stress block exactly equivalent to the Eurocode 2 parabolic-rectangular stress … Continue reading

Faster Biaxial Bending

The spreadsheet to calculate ultimate moment capacity of a reinforced or prestressed concrete section under combined axial load and biaxial bending, last presented here, has been updated to use the QuadBrent solver, rather than the Excel Goal Seek function, for … Continue reading

Equivalent Stress Blocks

Previous posts (e.g. Stress blocks in AS 3600) have presented Excel User Defined Functions (UDFs) that determine the ultimate bending strength of a reinforced concrete section with the use of a rectangular concrete stress block, with depth and stress factors … Continue reading
