Feedback form is now closed.
In this work, the optimal design of an intermediate support of a beam structure is investigated for the purpose of controlling the reaction forces such that the excessive vibration loads transferred by the restraint supports can be reduced considerably during the vibration situation. By use of the differential transformation method, it is convenient to solve the differential vibration equation of the beam and obtain the restraint reaction forces of the supports. First, the influences of the intermediate support position and stiffness on the restraint reaction forces are studied. Then, the optimum design of the support position and stiffness of a beam structure is performed based on balancing the reaction forces in the restraint supports under the foundation excitations. Finally, an illustrative example is provided to show the effects of the optimal support design for balance of the restraint reaction forces under different excitation frequencies.
