Abstract : A detailed description is given of a computer program to carry out a general first order elastic analysis of any type of plane frame. It is capable of analyzing pinned or rigidly jointed frames, or mixtures of both systems. Shear and axial deformations may be taken into account in rigidly jointed frames. In addition, strains caused by temperature changes, shrinkage or lack-of-fit can be allowed for with little extra effort in data preparation. The source program has been written in the Fortran language so that it can be used on most currently available computers. Analysis is carried out by the displacement method so that considerations of frame redundancy do not arise. For a given machine there will be a maximum size of structure that can be accommodated, depending primarily upon the number and type of its members, the degrees of freedom of the frame, and the number of alternative load sets for which an analysis is desired. The program was developed to check the elastic behavior of a series of braced and unbraced multi-story steel frames being tested in the Fritz Engineering Laboratory of Lehigh University's Department of Civil Engineering as part of a program of research into the plastic behavior and design of multistory steel frames.
