Texto completoThe characterization of traffic loads is of great importance for pavement design, as well as for the measurement of performance in a pavement management system. The use of empirical approaches to determine the effects of traffic load on pavement structures, dating from the 1960\'s, presents serious limitations, since its results are just valid for the same or very similar intervening factors that prevailed at the time of its development. The traffic load factors and vehicle characteristics (axle type, tire type, tire inflation pressure, and suspension type) are quite different today from those existing 50 years ago. Given that the performance models are important tools of pavement management systems (PMS) to predict the evolution of pavement condition over time and/or accumulated traffic and therefore dependent on a consistent characterization of the traffic, the objective of this research was to analyze the effects of traffic characteristics on pavement performance through the generation of statistical models based on the concept proposed by the AASHTO 2002 method, axle load spectra of commercial vehicles, comparing them with the concept of load equivalence factor, developed through the AASHO Road Test in the 1950s. Data collected in 2008 in a weighing station located on Immigrant Highway - SP-160, km 28, southern runway, were used for the development of load spectra and subsequent modeling. Practical and statistical tests were performed to determine the variability of monthly vehicle-factors (FV) to the mean value for the year 2008. Despite the statistical analysis, performed by applying the Kolmogorov-Smirnov (KS) test, have shown significant differences between the monthly and annual spectra variation, there were not practical differences in the final thickness of the pavement associated to changes in vehicle-factors. Statistical models were developed for each vehicle class and for its axles, having been used Log-normal and Weibull probability distributions to model the load spectra. The model parameters were obtained from the method of least squares, complemented by the KS and chi-square tests, being important to mention that the coefficients of determination (R2) were greater than 0.90. The comparison between the results predicted by the models and the original data, made either by empirical and empiricalmechanistic approaches, with use of computer programs ELSYM5 and MEPDG, shows that the Weibull model is the most suitable for application in Brazilian highways with similar traffic characteristics to the Immigrants Highway.

Texto completoThis thesis is dedicated to the fatigue and damage tolerance analysis of the aircraft structures under gust loads. The fatigue and damage tolerance analysis is a significant issue in the aircraft structure design. It aims at defining the inspection program of the aircraft structure in order to ensure its safety through its entire life. The first part reviews the state-of-the-art in the various involved topics for the global process for fatigue analysis of aircraft structure under gust loads: the atmospheric turbulence modelling, the load and stress computation by a finite element analysis, the generation of the fatigue spectrum and at the end, the fatigue and damage tolerance analysis. The second part presents the whole process currently implemented at Airbus. The main strengths and weaknesses are pointed out and this en-ables the identification of several improvement axes. From the continuous turbulence model based on the Von Karman Power Spectral Density(PSD), the computed stresses are included according to statistics established from in-flight measurements in the fatigue spectrum in order to build a stress cycle sequence. The input data for the fatigue and damage tolerance analysis are obtained from the definition of the various fatigue mission profiles, the unitary stress values, the dynamic response of the structure and the turbulence statistics. In the third part,a new methodology is presented in order to obtaine efficiently and accurately the temporal stress sequences due to the atmospheric turbulence. This method relies on new results enabling the generation of correlated time signals from the PSD functions. First, the PSD of the various stress components are directly obtained from the Von Karman PSD via a finite element analysis. Then, the correlated temporal stress sequences are generated and distributed in the fatigue spectrum according to the turbulence intensity statistical law. This new process enables the improvement of the stress computation and the fatigue spectrum generation. It replaces the turbulence statistics by stress exceedance statistics which are defined by an analytical formula in a reasonably conservative way. In addition, the lead time to build the input data for the fatigue and damage tolerance analysis is significantly reduced. Results from the fatigue and damage tolerance analysis are presented in order to highlight the quality of the improved processes both in terms of accuracy and lead time
