2D and 3D Finite Element Models of Gatun Dam

<p data-end="490" data-start="195">This dataset contains two- (2D) and three-dimensional (3D) finite element models (FEM) developed in PLAXIS to evaluate the dynamic response of Gatun Dam under both harmonic and seismic loading conditions. It includes a total of 35 models: 21 two-dimensional and 14 three-dimensional.</p>

<p data-end="490" data-start="195">The 3D models cover the East and West Embankments, with a focus on the Chagres River paleochannels. The 2D models correspond to selected cross-sections aligned with the 3D models of both embankments.</p>

<p data-end="934" data-start="744">Harmonic loading simulations include three directional input scenarios for the 3D models (transverse, longitudinal, and bidirectional), while the 2D models are limited to transverse loading.</p>

<p data-end="1186" data-start="936">Seismic response models were developed using records from the 1989 Loma Prieta and 1985 Michoacán earthquakes. Both ground motions were scaled and applied following the Panama Canal Authority’s Seismic Evaluation Criteria for critical infrastructure.</p>
