摘要

Abstract

High-temperature performances of RC members and structures become important in fire-resistant design of RC structures. Calculations of temperature distribution of RC structures have been specified in some design codes. A standard for fire-resistant design of RC structures was issued in Guangdong, China. Current-ly, methods to obtain temperature field of RC structures include searching charts, numerical analysis, and test methods, which was suggested in Eurocode 2. Some simplified approaches were also proposed by different scholars. In this paper, four different methods were used to calculate temperature variation along the thickness of an 120mm RC slab. Comparisons between different methods were conducted. Result analyses of these cal-culating approaches result in an understanding of these methods.
