DEVELOPMENT OF SHRINKAGE AND CREEP PREDICTION MODELS FOR HIGH PERFORMANCE CONCRETE BY FAST-ACCESS CLOUD-BASED DATABASE

Abstract

This study presents the first analysis system and fast-access cloud database for shrinkage and creep of high-performance concrete in the world, named “shrinkage and creep database in Taiwan”, SCDT. SCDT not only has the most comprehensive experimental data, including NU, JSCE, Europe and TW database, but provides design tool for researchers and engineers. It can further facilitate the development of prediction models for localized concrete. Users can obtain the shrinkage and creep curves based on their selected prediction models in SCDT. Comparisons of predicted results of selected models and test results in chosen database can be generated in seconds. Examples of development of shrinkage and creep prediction models in Taiwan based on model B4 by using SCDT to reflect high performance concrete characteristics in Taiwan is also presented in this study. Users anywhere in the world can easily access SCDT to browse and upload data, receive predictive results, or develop predictive models.
