Simulation of Cantilever Column under the Isolation Device Considering Additional Moment

Abstract:

To accurately simulate the second-order bending moment caused by the superstructure shift in the isolation system is difficult. A simulation method of considering the second-order moment is put forward in this paper, and which is used to obtain the push-over curve of the cantilever column. Comparison of the push-over curves that with or without considering the additional moment is shown in this paper. The comparison presents evidence reduction, and embodies the decrease of stiffness. This simulation method can effectively balance the affection of the upper structure shift to the vertical bearing member under the isolator.
