Abstract
In recent times, occurrences of fire accidents in buildings have become more frequent. To avoid such situations, the effects of fire need to be incorporated into structural design and detailing. In this study, the structural behavior of fire-exposed flexural elements is assessed at elevated temperatures and fire rating is determined in accordance with different methods of Eurocode-2. Structural moment capacity is also evaluated by incorporating the procedure of simplified calculation methods present in Eurocode EN 1992-1-2:2004. In this study, Wickstorm’s method and transient thermal analysis using ANSYS are used for estimating temperatures in fire-exposed RCC members. Fire ratings obtained from the simplified calculation method and advanced calculation method of EN 1992-1-2:2004 is compared to fire ratings recommended in IS 456:2000 codal provisions.
