dc.description.abstractFires, which cause life and material loss, result in a decrease both in strength of concrete and steel and moment capacity of reinforced concrete (RC) members. Reinforced concrete (RC) beams are also affected by heat and a decrease in the moment capacity occurs. To investigate hazardous effects of high temperature, temperature distribution, and internal forces in the investigated cross-sections are required. In the present study, the temperature acting on section surfaces is calculated by the equation given in ISO834. The temperature distribution within the section is defined using Laplace temperature transmission equation and losses in the strengths of materials are determined using the given formulation in Eurocode2. The heat conduction equation is solved by finite difference method, and the temperature distribution in small pieces inside the cross-section is obtained. The tensile and compressive forces are calculated using the decreased strengths of materials in small pieces inside the cross-section. Later, the moment capacity is calculated using equilibrium equations. Additionally, a practical method is suggested to determine temperature-distribution in RC beams with T-section. Efficiency of the suggested practical method and negative effects of high temperature on moment capacity of beams are investigated. According to the obtained results, it is observed that the suggested practical method is quite effective to determine temperature-distribution in T-sections, and bending capacity of the cross-section decreases significantly with increasing fire exposure time.
