Abstract
In order to investigate the compression creep of two kinds of high-performance concrete mixtures used for prestressed members in a bridge, an experimental test under laboratory conditions was carried out. Based on the experimental results, a power exponent function was used to model the creep degree of these high-perform-ance concretes (HPCs) for structural numerical analysis, and two series parameters of this function for the HPCs were given with the optimum method of evolution program. The experimental data were compared with CEB-FIP 90 and ACI 92 models. Results show that the two code models both overestimate the creep degree of two HPCs, so it is recommended that the power exponent function should be used for the creep analysis of bridge structure.关键词
