AI Technical Summary
In the existing technology, when using WEN elements to establish a first-order rigid ordinary differential equation to calculate the horizontal frictional resistance of a frictional oscillating support, it is necessary to perform step-by-step integration, which results in a large computational workload and large fluctuations in the frictional resistance calculation results when the integration step size is large.
By obtaining the maximum frictional resistance of the support and the sliding speed of the support within a set time period, an iterative model between the frictional resistance of the frictional swing support and the sliding speed of the support is established. Based on the changes in the sliding speed and displacement of the support, the horizontal frictional resistance of the frictional swing support within the set time period is determined.
The problem of fluctuation in friction calculation results has been solved, computational efficiency has been improved, and convergence of boundary nonlinear dynamic time history analysis has been supported.
