Fuzzy-Based Approach to Predict the Performance of Shear Connectors in Composite Structures [PDF]

Journal of Soft Computing in Civil Engineering, 2019
Shear connectors in steel-concrete composite frames are essential elements to transfer the shear between steel and concrete. Several parameters must be considered in predicting the strength of these connectors.

Fatigue behaviour of composite girders with composite dowels assuming randomly distributed input parameters

Steel Construction, 2022
AbstractNominated for Eurosteel 2021 Best Paper AwardThe fatigue design of shear connectors for composite girders is based on fatigue strength curves (with 95% survival probability) derived from tests with one or just a few connectors. According to the Eurocodes, the lifetime of a girder can then be limited by failure of the shear connector with the ...
