Cubic Spline Update
The previous post in this series presented a User Defined Function (UDF) to fit a cubic spline to a series of points defined by XY coordinates. Each segment of the resulting spline is defined by a separate cubic curve, which may be … Continue reading
Reinforced Concrete Moment-Curvature – 2; Shrinkage and Creep
The previous post in this series provided an Excel User Defined Function (UDF) to find the short term curvature of a reinforced concrete section subject to combined bending and axial load. In this post UDFs will be presented to determine the strain … Continue reading
Reinforced Concrete Moment-Curvature – 1
The flexural curvature of any beam composed of material with linear elastic behaviour, subject to a bending moment, M, is given by: C = M / EI where E is the elastic modulus of the beam, and I is its … Continue reading

Reinforced Concrete Section Analysis – with prestress
The simplified reinforced concrete section analysis spreadsheet presented here has been revised to allow the input of a pre-tension stress to either or both layers of reinforcement. The spreadsheet (including full open source code) can be downloaded from RC Design Functions5. Note … Continue reading

Three UDFs
This post is in response to recent discussions at Daily-Dose-of-Excel where many and various worksheet formulas have been suggested to carry out tasks that are (it seems to me) better done with a simple User Defined Function (UDF): Adding Every … Continue reading
