Diagnosis of the metal tank under embankment, of the reinforced concrete tank, of the foundation piles and of the soil. Suggestions for areas for improvement. Following an on-site visit and a documentary analysis, a 3D finite element model was developed, and a linear elastic calculation was carried out to carry out the diagnosis of the earthquake resistance of the reservoir under slope, of its withdrawal line. , the peripheral reinforced concrete structure, the foundation piles and the soil. The 3D model was developed with wire-frame finite elements (beams, piles, draw-off and purge lines), surface (tank cover, walls and reinforced concrete slab) and volume (sand of the slope). The dynamic study was made on the basis of a modal-spectral analysis. Post-processing of the results made it possible to assess the resistance of the structural elements and the overall stability of the structure. Two soil configurations were studied to take into account the possibility of liquefaction of the upper soil layer. Proposals for areas for improvement have been proposed, ranging from more detailed non-linear analysis to proposals for reinforcement work. The seismic study carried out complies with the requirements of the decree of October 4, 2010. 3D view of the mesh without slope Mesh section without embankment Global view of the model with embankment Travel under operating expenses Envelope accelerations Pile diagnosis Soil resistance study Diagnosis of withdrawal and purge lines NECS Copyright 2017 Legal Notice Sitemap Contact By continuing to browse this site, you accept the use of cookies for audience measurement purposes.
