 ## Beam Elements in MASTODON
 
-Geometrically nonlinear beam and lumped mass/inertia elements have been recently added to MASTODON. These elements can now be used to approximate structures using stick-mass models. As a test scenario, stick-mass model of a nuclear power plant from the SASSI manual ([image001]) was modeled using MASTODON and LS-Dyna. The first 15 natural frequencies of the MASTODON model agree well with the SASSI and the corresponding LS-Dyna models, and the spectral acceleration at a location on the structure matches well with the LS-Dyna results as shown in [image002].

 The Facility Risk Group is setting up the Structural Dynamics Laboratory (SDL) at INL to collect data by conducting a series of experiments. The first set of experiments focus on the interface behavior of soil and structures. For this purpose, a reaction frame has been designed to house a soil box and two high capacity actuators. The data is collected by state-of-the-art equipment including slip sensors, string potentiometers, load cells and high-resolution cameras. The collected data, along with the existing literature, will be the basis for the soil-structure interface models that will be integrated to MASTODON.
