AS 3600 and RC Design Functions 8.01
The updated RC Design Functions spreadsheet (presented here) included an updated UMom function to find the ultimate strength of a rectangular section under combined bending and axial load; but I omitted to include the revisions to the alpha2 and Gamma … Continue reading

New AS 3600 and RC Design Functions 8
A revised version of the Australian Concrete Structures code, AS 3600, was recently published, with many significant changes, including: Changes to ULS reduction Factors Creep and shrinkage Curvature and deflection calculations Crack width calculation and stress limits Major changes to … Continue reading
Composite Beam Spreadsheet Update 1.01
Following a comment here, I have modified the Composite Beam spreadsheet to correct the stage 1 stresses forces in the reinforcement as listed in Columns 6 and 7, when the tensile face is the top. The output has also been … Continue reading

Stress increments in prestressed concrete beams
The two main Australian Standards covering prestressed concrete structures (AS 3600, Concrete Structures, and AS 5100 Part 5, Concrete Bridges) put a limit on the allowable increase in stress in reinforcement and prestressing strands and tendons, when the load increases from … Continue reading
