Abstract: Nailed shear connections are a new alternative type of shear connection in composite columns with concrete filled circular and rectangular tubes. The main advantage of a nailed shear connection is, that it can be applied from the outside of the tube without any prefabrication efforts. Based on the behaviour derived experimentally from push-out tests, proposals for the design resistance of nails for ultimate and serviceability limit states are made, providing provisions with regards to minimum steel thickness, concrete grade and nail spacing are fulfilled. In order to get a more realistic knowledge of the deformation behaviour in serviceability limit states, the combined shear resistance of the nails and the shear strength due to bond and friction and including long-term effects has to be considered. The background of a corresponding test program will be discussed.
