dc.description.abstract[SPA] En la tesis doctoral "Modelos de comportamiento seccional de hormigón armado ajustados a ensayos mediante algoritmos metaheurísticos" se proponen unas expresiones de comportamiento seccional capaces de proporcionar aspectos relativos a los estados de plastificación y último de secciones rectangulares de hormigón armado, como son el momento, la curvatura y el giro. Dichas expresiones se obtienen calibrando unas expresiones previamente propuestas en la literatura científica con ensayos experimentales correspondientes a vigas y pilares de sección rectangular. En el proceso de calibración se emplean técnicas de optimización basadas en algoritmos metaheurísticos.es_ES
dc.description.abstract[ENG] Modelling concrete structures requires the implementation of numerical models capable of reproducing the nonlinearity of this problem adequately. In particular, the seismic behaviour of these structures requires the application of different types of models, such as models of sectional behaviour, hysteresis models and global models, being the interaction between them essential to simulate the problem in an integral way. Seismic analysis of structures is a really time-consuming process, so that the models involved need to be accurate and efficient from the point of view of computing time. Therefore, it is important to obtain simple expressions that adequately reproduce the yield and ultimate behaviour of reinforced concrete sections, which is necessary to define the properties of the plastic hinges generated in the structure when acting the seismic load. Obtaining these expressions involves proper calibration with experimental tests. In particular, if these expressions must be calibrated by an extensive database, specific numerical procedures are required, such as those based on optimization techniques, in order to achieve an optimum adjustment between the values offered by the expressions and the experimental results. In this thesis, a database composed by more than 1000 experimental tests has been analysed and a set of tests is selected such that meet with seismic and construction requirements listed in the main construction codes; several empirical expressions relating to yielding and ultimate state of rectangular reinforced concrete sections have been calibrated; and the expressions obtained are implemented in the nonlinear analysis of several reinforced concrete frames, comparing the results obtained with different methods.en
