Faculty Civil Engineering and Geosciences Date 2001 Abstract The Art and Science of Model Building: A Bayesian Approach, by Prof. A. Der Kiureghian; The talk will describe a Bayesian approach to developing models, with special emphasis on limit-state models for reinforced concrete structures. The formulation can incorporate all kinds of information (theoretical models, laboratory experiments, field observations, statistics of basic quantities) and properly account for both intrinsic and epistemic uncertainties. Examples will be provided for reinforced concrete structural elements. Stratified Sampling Techniques in Extreme Value Analysis, by Prof. M. Yamaguchi; In the statistical analysis of data it is recommended to separately analyze the data from different seasons and/or different origin. The availability of stratified sampling techniques in the extreme analysis to the measurement data of winds and waves is discussed, in which the comparison is made between the return values and their variances estimated from annual maximum data and those from stratified maximum data. From Monte Carlo simulations it appears that the increase of the number of stratum does not necessarily improve the accuracy and the efficiency in the estimates of the return values. Dealing with Strength Degradation in Structural Reliability, by Prof. C. Guedes Soares; Typical degrading phenomena of civil structures are corrosion and fatigue. Maintenance will compensate for the degrading effects and is performed during the structures' lifetime following criteria that have evolved with time. This presentation will review the main types of probabilistic models and reliability techniques that have been used to model the time varying structural reliability, that results for the progression of fatigue and corrosion, including the changes that occur as a result of inspections and repair actions.
