| Abstract: |
The research considers the influence of fatigue failures of shear stud connectors on the overall reliability of steel-reinforced concrete superstructures. There are considered possible models of failures of the joint members and steel-reinforced concrete superstructures as a whole both for the First (Ultimate} Limit State (ULS} and for the Second (Serviceability} Limit State (SLS}. There have been developed scenarios for excluding joint members from the operation of the superstructure and a list of basic scenarios and levels of their progress has been compiled. For five models of road bridges steel-reinforced concrete superstructures, there was conducted a numerical experiment to simulate the exclusion of joint members from the work of the structure. The calculation results for each scenario and scenario level are analyzed with regard to possible structural failures. There are also drawn conclusions about the risks of violating the normal operation of superstructures due to the exclusion of the joint members from operation. |
