and deformation capacity of fire-damaged high strength concrete (HSC) columns. LENWARI et al [14] found that the exposure temperature has a significant influence on the compressive strength of concrete after a fire. Wrapping with CFRP can enhance the compressive strength of the concrete at high temperatures. LIU et al [15] experimentally concluded that CFRP confinement significantly affects......
