ALL SUPPORTS USED IN CIVIL ENGINEERING ARE TO BE INCLUDED IN A NEW STANDARD (DIN 4141). THERE IS A LACK OF ACCURATE DATA ON THE DETERMINATION OF PERMISSIBLE HORIZONTAL STRESSES (ON NON-ANCHORED SUPPORTS). THE OBJECT OF THE STUDY IS TO DETERMINE COEFFICIENTS OF FRICTION BETWEEN SUPPORTS AND NEIGHBOURING STRUCTURAL PARTS UNDER STATIC AND DYNAMIC VERTICAL LOADING, AND TO ESTABLISH PERMISSIBLE LIMIT VALUES.
