## 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 model structures using stick-mass models. As a test scenario, a 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].
