Load carrying capacity of cracked concrete railway sleepers
Luleå University of Technology, Department of Civil, Environmental and Natural Resources Engineering, Structural and Construction Engineering.ORCID iD: 0000-0002-0560-9355
2008 (English)In: Structural Concrete, ISSN 1464-4177, E-ISSN 1751-7648, Vol. 9, no 3, p. 153-161Article in journal (Refereed) Published
Abstract [en]

The load carrying capacity of damaged prestressed concrete railway sleepers has been investigated in order get information about how the cracking influences the remaining load carrying capacity compared to an un-cracked sleeper. The following tests have been performed: bending capacity of the midsection, the rail section, horizontal load capacity of the fastener, control of the concrete properties and fatigue capacity in bending of the rail section. A visual inspection and classification of the damages are also presented. The test results have been compared with calculations according to the Swedish railway code for sleepers and show that railway sleepers are quite robust. Small cracks do not seem to influence the load carrying capacity and it is first when the cracking is very severe that the load carrying capacity is reduced significantly.
