Numerical Study on Thermal Performances of Fully Encased Composite Column
Composite columns are structures comprising of concrete, steel, and reinforcing bars. They have several advantages over conventional columns in terms of load carrying capacity, seismic performance, and fire resistance. In this paper, an attempt is made to evaluate the thermal performances of fully encased composite column using numerical method. Thermal analysis of composite columns with built-up I and T steel sections was carried out using ISO 834 fire curves. Parametric studies were also done to understand the role of pre-loading, grade of concrete and cross section of composite column subjected to fire loading. Results suggest that the shape of steel section, grade of concrete, nature of pre-loading, and cross-sectional area of the column have significant effects on the thermal behavior of fully encased composite columns.
