Paper Title:
Residual Bearing Capacity of Reinforced Concrete Member after Exposure to High Temperature
  Abstract

After boundary conditions of member and thermal parameters of materials are determined, ANSYS software is utilized to analyze the maximum temperature distribution in the member under different fire duration. The equivalent cross-section economization method is given to calculate residual bearing capacity of RC member after exposure to high temperature, here, strength of reinforcement is considered as invariant, and the original section area is regarded as reduced. The numerical results are in good agreement with the experiment results of other reference, so appliance of the method is proved, Based on these, some parameters have significant influences on reduced coefficient of residual bearing capacity, such as sectional dimension, fire duration time, strength of reinforcement and concrete,ratio of reinforcement,thickness of fire-protection layer, which are analyzed and theory basis is supplied on safe monitor, repair and reinforcement of RC member after exposure to high temperature.
