A STUDY ON TWO INTENSITY CLASSES OF SNOW-FALL DEPTH, WIND VELOCITY AND EARTHQUAKE ACCELERATION BASED ON ORDER STATISTICS : Load models for use in ultimate and serviceability limit states design [II]

Abstract

A probabilistic method to determine two classes of load models for use in safety and functionality limit state design based on order statistics of basic variables (hazard intensity) was presented in the previous paper. Applying the method, two classes of hazard intensity are evaluated and the probabilistic characteristics of the hazard models are discussed. Snow-fall hazard and wind hazard are dealt as annual occurrence time-series in which the annual maximum intensity of snow-fall depth and wind velocity are used as the basic variates. Earthquake hazard are dealt as Poisson occurrence time-series and the earthquake acceleration estimated from historical seismic data are used as basic variables.
