K11 value for HST3 fixings
To check combined utilisation for tension and shear loads using supplementary reinforcement in accordance with BS EN 1992-4:2018 7.2.3.2 equation 7.57, i require a value for k11. Please could you advise the k11 value.

Thank you for your question. I'm assuming you have checked the ETA for the HST3 and haven't found a publish K11 value. So in such cases EC2 Part 4 7.2.3.2 (7.57) also states the following: If no value for K11 is given in the relevant European Technical Product Specification, K11 = 2/3 may be assumed. This is based on engineering considerations and is considered as conservative.
