Using Beam Design Functions

Posted on September 7, 2011 by

“Beam Design Functions” is an Excel spreadsheet providing a User Defined Function (UDF) that will calculate the stresses, strains, forces and moments in a reinforced or prestressed concrete section subject to any specified bending moment and axial load, using an … Continue reading →

Reinforced concrete elastic analysis; Circular section

Posted on April 24, 2010 by

Previous posts have presented the theoretical background to finding stresses and strains in a reinforced concrete section built up of trapezoidal layers and subject to combined bending and axial loads.  A spreadsheet with User Defined Functions (UDFs) and open source code … Continue reading →

Reinforced Concrete Section Analysis – with prestress

Posted on October 25, 2009 by

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 →

Reinforced Concrete Section Analysis 7 – rectangular sections

Posted on November 5, 2008 by

Previous post The spreadsheets presented in earlier posts in this series have been simplified for use with rectangular sections with two layers of reinforcement.  The functions EStress (for elastic analysis of stresses, strains and crack widths) and UMom (for the … Continue reading →

Reinforced Concrete Section Analysis – 5; Ultimate Limit State

Posted on August 19, 2008 by

Previous posts in this series have looked at the analysis of beams where the steel stress is within the elastic range, and the concrete stress is sufficiently low that the assumption of linear elastic behaviour in compression is a reasonable approximation.  … Continue reading →
