A numerical method to identify thermal conductivity from time history of one-dimensional temperature variations in thermal unsteady-state is proposed. The numerical method considers the change of specific heat and thermal conductivity with respect to temperature. Fire test of reinforced concrete (RC) columns was conducted using a standard fire to obtain time history of temperature var... https://www.jmannino.com/top-offer-Simply-Southern-World-Full-Valentine-T-Shirt-top-buy/
