Time-dependent methods of analysis for colums, stiffened and unstiffened plates, and torsional members have been developed and programmed for the IBM 709 digital computer. The important material behaviors, id est, soaking at temperatures, elastic and plastic strain, creep and residual stress and strain under varying temperature inputs, can be accounted for in the digital solutions. Two illustrative examples for obtaining allowable stresses are shown; the first for a stable structure in combined tensile and bending and the second for a column subjected to time-dependent displacements due to creep. These two examples are sufficiently typical to demonstrate the applicability of the procedures developed in this report or other procedures which give the stress-strain-deflection time history of a structure.
