Studies on Presumptions of Heated Temperatures and Residual Bearing Forces in One-dimensional Concrete Members Suffered from Fire

Abstract

In the assesment of a firedamaged building built in reinforced concrete, it is very important to estimate the residual bearing force of each member after fire. Accordingly, in order to estimate the residual bearing force, the heated temperatures in concrete must be grasped. The authors calculated the heated temperatures in onedimensional concrete members after fire by easy method and compared calculated values with experimental ones. And moreover, they analyzed the quadratic regressions with the former values and made the presumed equations of heated temperature distributions. In conclusion, they presumed the residual bearing forces of the members using the equations
