| Abstract: |
Reinforced elastomeric bearings can be used as high quality vibration isolators for buildings, the separation of different sections of buildings or isolation of heavy machines. In contrast to the static behavior of elastomeric bearings the construction codes do not provide formulas to calculate their dynamic behavior. Extensive tests are required to specify the dynamic stiffness of bearings being essential for the optimization of the efficiency of isolation applications. Thepresent paper describes the procedure of the calibration of a set of semi empiric formulas to describe the dynamic behavior of reinforced elastomeric bearings. The basis of this calibration is given by static and dynamic measurements on ten different bearing types. |
