PROBABILITY METHODS IN SEISMIC ENGINEERING

METHODS PROBABILISTICOS EM ENGENBARIA SISMICA

By making use of concepts of the Theory of Probability, the definition of probabilistic models for seismic loading is studied, with special emphasis for the stationary model. Starting from the properties of the model, some important statistics of the response of the linear oscillator, with a degree of freedom, are presented, namely the statistics of the maximum values, within an interval of time. These results allow easy generalization to the linear oscillator with N degree of freedom, and the working out of a program known as "Statismax". Finally, by using a branch of the theory of Markov processes, that of the diffusion processes, the response of a nonlinear oscillator to a white noise loading in determined, the results obtained being compared with those presented by other authors. /Author/
