Strategy for eliminating high-frequency instability caused by multi-transmitting boundary in numerical simulation of seismic site effect
نویسندگان
چکیده
A multi-transmitting boundary is a local artificial widely used for numerically simulating seismic site effects. However, similar to other boundaries, the has instability issue in numerical simulation. Based on concept of multi-directional transmitting formula, strategy eliminating high-frequency studied and measure proposed using neighbour node realize smoothing filtering. The verified through analysis. coefficient chosen this provides reference deriving multidirectional formula time domain.

Seismic site effects in a deep alluvial basin: numerical analysis by the boundary element method
The main purpose of the paper is the numerical analysis of seismic site effects in Caracas (Venezuela). The analysis is performed considering the Boundary Element Method in the frequency domain. A numerical model including a part of the local topography is considered, it involves a deep alluvial deposit on an elastic bedrock. The amplification of seismic motion (SH-waves, weak motion) is analyz...
متن کاملAnalysis of Multi-transmitting Formula for Absorbing Boundary Conditions
In this paper, we analyze the multi-transmitting formula (MTF) proposed by Liao et al [19]. From the computed reflection coefficients for the fully discrete MTF boundary conditions, we suggest choices for the artificial wave propagation speed, which are different from Liao’s original choice. Theoretical and numerical studies for various incidence angles demonstrate that the suggested choices ef...
