【Abstract】 The restraint conditions and thermal regimes are analyzed, which govern effects on the responses of structure in fire. A simple beam behavior in fire is simulated by the finite element method. The conclusions are important and useful for analyzing and interpreting behavior of large and sophisticated structures in fire. These provide basis for fireresistance design method based on the whole structure.更多还原
