Creep Design Aid: Open-Source Website Program for Concrete Creep and Shrinkage Prediction

To facilitate the calculation of creep and shrinkage properties needed for analyzing the creep and shrinkage effects in structures, an open-source creep design aid program has been developed and is made freely available on a website. It is based on Model B3, but can be easily adapted to other creep and shrinkage prediction models. Based on the given strength and the main characteristics of the given concrete, the program calculates, plots, and tabulates the compliance function, relaxation function, creep coefficient, aging coefficient, and creep rate function. For ease of use, there is a user-friendly graphical user interface. The program also uses Latin hypercube sampling to calculate 95, 90, or 85% confidence limits of the response curves from given coefficients variations of input data, and performs updating of long-term prediction based on given short-time test data, using either linear regression or Bayesian estimation.
