Floor vibration due to machines operations
In one case undertaken by RE, it was found that machine vibrations during the operations caused strong vibrations to the floor underneath. Thus, accelerometers were used to capture real-time floor and machine vibrations for all axes. Further, floor acceleration was double-integrated to floor dynamic displacement, as well as floor static displacement due to static floor self-weight, machine weight and floor live load, carried out by FEM programming to determine total floor displacement. Consequently, the floor safety was assessed.
