Ideal for highly nonlinear scenarios, including structural collapse, severe damage, soil-structure interaction, and blast loading. 2. Key Methodologies for Abaqus Earthquake Analysis
For wave propagation problems—including earthquake analysis of large structures—mesh density must be sufficient to capture the highest frequency content of the ground motion. As a rule of thumb, the element size should not exceed one-tenth to one-twentieth of the shortest wavelength of interest. For a maximum frequency of 10 Hz and a shear wave velocity of 300 m/s (typical for medium-dense soil), the shortest wavelength is 30 m, dictating a maximum element size of 1.5–3 m. abaqus earthquake analysis
