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