Furthermore, recent studies 10 have reported that Eurocode 2: Design of Concrete Structures (hereinafter EC‐2) overestimates or underestimates shear strength depending on the type of aggregate or cross section involved and neglects some key contributions. 11 These facts suggest that there is still no universally accepted simplified mechanical Today research on creep and shrinkage of concrete is diversified to such a degree that specialists working in different areas sometimes find it difficult to understand one-another.

Railway networks are exposed to various environmental conditions. It is thus critical that infrastructure components can tolerate such effects by design. Railway sleepers are a critical safety component in ballasted track systems. Prestressed concrete is currently the most common material for railway sleepers due to its superior advantages in structural performance, low maintenance

The theory of concrete creep and shrinkage has not been regarded as part of what has been understood as damage mechanics.

Time-Dependent Behaviour of Noncomposite and Composite Prestressed Concrete Structures Under Field and Laboratory Conditions"q Ph. Time-Dependent Deflections of Prestressed Concrete Beams"v Highway Research Board BulletinPre-stressed concrete (PSC) girders have been widely adopted as superstructures for high-speed railway bridges; the long-term deflection of bridges with PSC girders is known to be dependent on the mechanical responses of concrete, such as creep and shrinkage .Concrete creep and drying shrinkage are time-dependent deformations, caused by sustained loading (e.g., dead load), and loss of Creep and shrinkage of concrete may lead to excess long-term deflection in concrete members, especially in prestressed concrete structures.
