Abstract

A method of obtaining a set of closed-form solutions for reliability acceleration factors under time-varying temperature/humidity environments is presented. This paper outlines the procedure for generating such equations based on National Oceanographic and Atmospheric Administration climatic data. Results from Phoenix, Arizona are used as a case study. Predictions from these closed-form solutions are compared with traditional reliability assessments and exact solutions using raw ambient temperature and humidity values.
