Effect on the Push-over Curve of Cantilever Column FEM under the Isolation Device Considering Additional Moment

摘要：

The push-over method can be adopt in the design process of cantilever column under the isolation devices, but to accurately simulate the second-order bending moment caused by the superstructure shift is not easily. A 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 with the push-over curve that without considering the additional moment present evidence reduction, which embodies the decrease of stiffness. This method can effectively balance the affection of the upper structure shift to the vertical bearing member under the isolator, which can extend to other similar components.
