Do you want to perform earthquake analyses according to design codes or just in order to verify your structure? The current article describes in great detail two different approaches; the static (response specter) and the transient approach

Earthquake analyses can be performed by applying different procedures. The most popular procedure is the Response Spectrum analysis (RS-analysis). The RS-analysis is cheap to use in terms of numerical costs as it is based on modal results. However, the spectrum solution can only show positive results, i.e. positive stresses and strains, as it only records the maximum amplitudes for each mode and the superposition of these results in turn will give the positive results.

Another procedure is to perform a full transient analysis of the earthquake. Such analyses are computational expensive. However, they will give results based on the dynamic equation of equilibrium and hence both positive (tensile) and negative (compressive) stress results will be reported for the full length of the earthquake. In this tutorial a shell structure will be used to show how such analysis can be run in ANSYS Workbench.
