Connection slip in composite elements under quasi-long-term actions

The paper presents procedures of the slip calculation in steel and concrete composite structures under quasi-long-term load with flexible stud connectors. To describe the slip relation s = s (P), exponential functions are used as appropriate for using in engineering practice. The former already existing expressions for calculating the slip for short-term loads were generalized. The values of factors for the formula were determined on the basis of the experimental investigation
