Damage of prestressed concrete railway sleepers and its impact on durability
(International Conference Modern Building Materials, Structures and Techniques (MBMST 2019), 2019)Prestressed concrete railway sleepers are the most widespread sleepers due to their stiffness and high bearing capacity. They transfer train induced loads from the rails directly to the ballast and therefore are the most ... -
The effect of concrete creep on the long-term tension-stiffening law and prediction of a time-dependent inertia moment of the cracked RC flexural cross-sections
