Reinforced Concrete Moment Curvature – Development over time

Posted on August 28, 2015 by

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 →
