Synopsis:

Factors influencing creep and shrinkage of concrete. Main features and effects of creep and shrinkage of concrete. Increase of deflections and redistribution of internal forces. Structures changing structural system and second order effects. Time development of the humidity and temperature distributions in concrete members. Environmental conditions and analysis of temperature and humidity transfer. Non-uniformity and time development of humidity distributions. Strain softening. Stress analysis. Creep and shrinkage prediction models. Calculation of strain from a known stress history. Direct integration and methods of time-discretization. Analysis of stress variation with known strain history; relaxation. Creep and shrinkage analysis of structures. Structural analysis of statically determinate and indeterminate structures, homogeneous and non-homogeneous, changing structural system. Methods of structural analysis. Redistribution of internal forces. Stress variation in concrete structures subjected to support settlements. Stress distribution in box girders. Creep analysis of high-rise buildings. Creep buckling. Excessive deflections of prestressed concrete bridges. Findings from experimental investigations. Measurements of stress and deflection developments. Comparison of experimental results with theoretical predictions. Statistical variability of material creep parameters and environmental factors. Uncertainty of creep predictions. Variability of stresses and deformations. Conclusions and practical recommendations.
