Presented is a computer program for the input of creep and shrinkage properties for a structural analysis program. The program either accepts numerical data on the compliance function and the shrinkage function at discrete load durations and ages at loading, or uses the recent BP Model for creep involving the double-power law. The most useful characteristic is the availability of thirteen different options for specifying the creep and shrinkage parameters; sealed conditions or drying conditions, creep values specified and interpolation to be used, parameter of a creep formula specified, or creep formula automatically fitted to given creep data, short time data specified and extrapolation done by a formula, etc. In addition to returning the compliance function, the program also calculates the relaxation function and the age-dependent elastic moduli of a Maxwell chain model that is equivalent to the given creep properties. The program is particularly suitable for the input of creep characteristics for a large-scale finite element analysis.
