000019144 520__ $$2eng$$aExperimental and numerical studies have shown that fire damage negatively influences the seismic performance of reinforced concrete structural members. This paper investigates damage indices that quantify the influence of fire damage on the lateral stiffness and the lateral-load bearing capacity of RC structural walls. The damage indices are based on the fire damaged material properties of concrete and reinforcing steel for the wall section, and are on a scale ranging from zero to unity, where unity represents the undamaged state of a wall section. The post-fire seismic performance of sixteen RC structural walls are analyzed using a validated simulation method under sequential fire-earthquake loads. The numerical load-bearing capacity and stiffness of walls under lateral loads and the damage indices of wall sections are calculated. Preliminary relationships between the damage indices and the numerical post-fire seismic performance of RC structural walls are established. Those proposed relationships help in assessing the post-fire performance of RC structural walls based on the damage indices.
