| Abstract | ||
| The study of nonlinear response of steel buildings under elevated temperatures from fire loading can be achieved by sequentially using heat-transfer analysis and stress analysis. By means of finite element analysis represented by the commercial finite element (FE) software ANSYS both thermal and structural response of composite concrete beams exposed to fire has been set up. The proposed three-dimensional FE model is able to simulate the overall flexural behavior of simply supported composite beams subjected to either concentrated or uniformly distributed loads in combined with temperature effect. The bond between the top flange of the steel beam and the concrete slab was assumed to be rigid in this model. | ||
