For decades, KÖCO shear connectors have been used to anchor steel components in solid construction. They transfer forces and torques in any direction from the steel part into the concrete. The positive connection of the shear connector secures the transmission also in the tension zone of the concrete. Very fast welding of the shear connector with the proven KÖCO stud welding systems is an important factor for safety and efficiency of the connection.
Steel components with welded-on KÖCO shear connectors are subject to building regulations in terms of manufacture and assembly in European Technical Assessments (ETA-03/0039 for structural steel and for stainless steel). The basis for this is European Assessment Document 330084-00-0601 "Steel plate with cast-in anchors".
The design is carried out in accordance with CEN / TS 1992-4: 2009 "Design of fastenings for use in concrete". The change to the 2019 publicized standard EN 1992-4 is planed. For dimensioning we offer the program "StudCalc Pro"; it designs steel components with welded-on KÖCO shear connectors according to the current standards
With the update to version 3.1.1 StudCalc Pro does not only offer the verification of steel components with welded-on KÖCO headed studs according to the current rules, but also the possibility to verify fasteners with KÖCO headed studs for fatigue, e.g. crane runways.
In EAD 330084-00-0601 (European Assessment Document "Steel plate with cast-in anchors"), the basic document for ETA-03/0039 (European Technical Assessment), the fatigue design is not regulated for formal, non-technical reasons. According to ETA-03/0039, which was valid until June 2018 (European Technical Approval), KÖCO shear connectors were also allowed to transfer fatigue-relevant loads.
We therefore offer users the possibility to carry out a state-of-the-art fatigue check for KÖCO shear connectors welded to anchor plates based on the values valid until 2018 from ETA-03/0039 dated 04 June 2013.
The following features make working with StudCalc Pro easy:
