Available experimental techniques (static loading testing, operational modal analysis, etc.) together with the development of corresponding finite element model make posible to have reliable virtual models for assessment. Once the model is updated, issues such as semi-rigidity of the joints, expected cumulative damage in the lifetime, vulnerability, utility of embedded sensors, efficiency of passive control devices as TMDs or suitability of specific reinforcements can be addresed. For non-deterministic loading (wind, waves, traffic, human induced loading, etc.) other methodologies than the simplified proposals from the codes can be carried out. Multiphysics fluid-structure simulations via CFD are more and more accurate nowadays. These methodologies have been successfully used to estimate lock-in phenomena in large industrial chimneys, interference effects between close masts and waves in tanks under seismic loading, among others.
Besides our own developed applications, we have professional licenses for simulation software, either directly or through partners. These include ANSYS-Fluent, SolidWorks, or ABAQUS between the general purpose finite element packages and other more specific ones as LS-DYNA, ANSA, FEMTools, Artemis, PAM-CRASH, GH_Bladed, QUEST, ROBCAD, DELMIA, Magmasoft and other products from Dassault Systems and from Altair.
