## Reinforced Concrete Moment Curvature – Development over time

I recently noticed that in the RC Design Functions spreadsheet the TimeCurve function had stopped working. The function calculates the development of reinforced concrete section curvature over time, and was previously presented in Reinforced Concrete Moment-Curvature – 3; Restrained Shrinkage and Creep and Reinforced … Continue reading

## Using RC Design Functions – 3

In the previous post in this series I looked at the results available from the EStress function in the RC Design Functions spreadsheet. Three associated functions are: EstressCap PLCurve TStiff EStressCap finds the maximum bending moment for a specified axial load, … Continue reading

## Daily Download 2: SLS design of reinforced concrete sections …

… and prestressed concrete sections. Today’s download installment covers spreadsheets for design of reinforced and prestressed concrete beams and columns at the Serviceability Limit State (SLS). The spreadsheets cover design of rectangular and circular sections, sections made up of any … Continue reading

## Reinforced Concrete Moment-Curvature – 4; Development of curvature over time

The previous post in this series looked at how specified shrinkage and creep strains affect the curvature of a reinforced consrete section subject to a constant load. In this post I will present a User Defined Function (UDF) that analyses … Continue reading

## Reinforced Concrete Moment-Curvature – 3; Restrained Shrinkage and Creep

The previous post in this series provided Excel User Defined Functions (UDFs) to find the strain in a concrete section due to unrestrained creep and shrinkage. In this post the effect of restraint of the creep and shrinkage strains by … 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

## Getting concrete shrinkage right

At the end of last year, very quietly, the commentary to the Australian Concrete Structures Code (AS 3600) was published. The commentary provides a wide range of explanatory and background information to the requirements in the main code, including some … Continue reading →
