水和反應 모델을 利用한 高强度 콘크리트 構造物內의 初期溫度履歷分布의 豫測에 관한 硏究

This paper presents the development of a computational program to predict the temperature distribution of high strength concrete structure members. The numerical simulation procedure starts with a hydration model that describes the evolution of cement paste microstructure as a function of the changing composition of the hydration products. The coefficients for the hydration model are determined with an artificial neural network technique. Temperature distribution is calculated using the three-dimensional finite element (FEM) analysis. Predicted temperature curves are compared with experimental data and a good correlation is found.
