On Faster Transient Analysis of Structural Systems Against Earthquakes: Case Study of An Earth Dam

The safety of large structural systems especially infrastructures against major earthquakes is of high importance. considering issues like nonlinearity of the behaviors in severe earthquakes, probable interactions with soil and water, size of the current computational models, and the everyday smaller digitization steps of recording devices, transient analysis against earthquakes is generally time consuming. to reduce this run-time, a technique was proposed in 2008 (soroushian, 2008), that replaces the earthquake record with a record digitized in larger steps. application of this technique to analysis ofmany structural systems has reduced analysis run-times without noticeably changing the accuracy (e.g. see (garakanienzhad & moghadas, 2015), when the enlargement scale, n, i.e.
