RELIABILITY THEORY OF DETERIORATING STRUCTURES

A method of analysis of the reliability for structures with resistance deterioration is developed. Random resistance of structures is assumed to deteriorate in proportion to the deterioration factor which is a function of the intensity of applied loads. In describing the survival of deteriorating structures, the nonfailure effect is also taken into consideration. Probability distribution of the residual resistance, failure rate, and reliability function for future loads are obtained for deteriorating structures with or without experiences of past loads of known intensities. Treatments of the problem herein are different from usual fatigue analysis because the residual strength after every load application is considered in an explicit manner and the problem in this study would be mainly concerned with a sequence of rare but very strong loads like seismic loads.
