Abstract

Strata

Strata performs one-dimension linear-elastic and eqivalent-linear (SHAKE type) site response analyses using time series or random vibration theory ground motions. Strata allows for stochastic variation of the site properties, including the: shear modulus reduction and material damping curves, shear-wave velocity, layering, and depth to bedrock.

The program can be run within the NEES platform, or installed as a desktop application.
