(2016) 23: 470-478 DOI: 10.1007/s11771-016-3092-2 Coupling model for calculating prestress loss caused by relaxation loss, shrinkage, and creep of concrete CAO Guo-hui(曹国辉)1, HU... with varying lengths (caused by the shrinkage and creep of concrete) might influence the final values and the time-varying function of the forecast relaxation loss. Hence, the effects of concrete......
Aging Coefficient, Creep Coefficient and Extrapolating Aging Coefficient from Short Term Test for Sealed ConcreteShrestha K MCollege of Civil Engineering, Fuzhou University摘 要:Aging coefficient and creep coefficient are important parameters for creep analysis of any structure. With the aim to obtain those parameters, an experimental investigation......
