Models Developed for Creep of High Strength Concrete

The aim of this research is to study the effects of creep in High Strength Concrete HSC. Creep known as a deformation of the structure under a sustained load and is one of the major deformations that concrete face. Moreover, the study explains how creep is predicted in HSC using various methods established by different codes and researchers. The research method consists of an extensive review of all relevant literature on creep and high strength concrete. The main issue is a comparison of observed creep distortions with seven present prediction prototypes to define which of the models most precisely predict creep while using two methods of curing, accelerated curing and standard curing. The findings from the research displays that “ACI 209 Modified” code is the most precise model of predicting creep in accelerated cure applications and the AASHTO-LRFD is considered the best model for the prediction of creep. The main conclusion to be drawn from this study is that the accelerated curing technique for high strength concrete causes a higher change in time-dependent strains than standard curing. The research method consists of an extensive review of all relevant literature on creep and high strength concrete. Keywords— Creep, HSC, Concrete Creep, Models Development of HSC Creep.
