Confinement of the core concrete using intermediate tie reinforcement is the best ways to improve column ductile behavior, to avoid buckling of longitudinal bars and used to confine the core concrete. It is important to assess the residual capacity of reinforced concrete columns that have been subjected to high temperature after lateral loading. The effect of thermal stresses and deformations on the performance of structural elements after earthquake loadings not treated in standard codes. The aim of this study is to investigate the response of RC columns subjected to high temperature and lateral loading. In this study analysis of reinforced concrete columns with different configurations of confining ties, strength of concrete and spacing of transverse reinforcement subjected to ISO-834 fire loading after constant lateral loading. Experimental result reported in the literature was used for validating the finite element model analyzed using ANSYS software program. The column was modeled as a cantilever column with square cross-section. After validation, parametric studies conducted on selected variables such as configurations of confining ties, spacing of transverse reinforcement and strength of concrete. A total of 19 column specimens 7 column specimens were modeled only applying gravity and lateral loads. One column specimen was without confining ties used as reference column. Other 11 column specimen was modeled considering fire loads in addition to gravity and lateral loading. The FEA results show that reinforced concrete column with intermediate confining reinforcement improve the load carrying capacity by 12.48%. Due to the effect of thermal stress, load carrying capacities of the confined and unconfined column by intermediate ties were reduced by 6.38% and 12.5% respectively. Increasing spacing of transverse reinforcement from 100mm to 300mm (i.e. 66.66%) decreases the strength by 4.22%. In other way the strength of concrete increases from 23MPa to 45MPa (i.e. 95.6%), the load carrying capacity of the column was increased by 14.74%.
