AbstractSome basic information concerning the deformation of solids is discussed briefly. In addition to presenting some practical data, a theory is also outlined. This theory may be characterized as an expansion of Dorn's creep theory into a form applicable to the calculation of deformation processes at variable temperatures and stresses. Rigorous and simplified techniques are described for the calculation of the deflection of joists and beams during fire exposure and temperature criteria of structural failure are developed. For an A 36 steel beam, for example, the criterion of failure is T(alpha c)=[70,000 divided by 45.62- 4.23(I[d]/I)]-460(in deg F). An obvious shortcoming of ASTM Methods E 119 is pointed out.
