Abstract:

This thesis discusses the types of bridge expansion joints certified for use in the Czech Republic and their disorders.
The first part was a theoretical evaluation of expansion joint failures. The second part focused on clarifying the failure of anchor bolts at the cantilever expansion joint. On the basis of determining the cause was then designed a method for determining the durability of expansion joints. Prognosis life cycles corresponds records according to administrator- repair works.

Keywords:

cantilever expansion joint, bolt connection, preload, fatigue bolts, heavy vehicles, corrosion cracking
