Abstract : The computer program CGRID, described in this user's guide, performs an analysis of planar grid structures using conventional matrix analysis techniques based on the assumptions of linearly elastic structural response to infinitesimally small displacements. The program is limited to structures with no more than 100 joints and 180 members. All members are assumed to be prismatic possessing straight centroidal axes and composed of a linearly elastic, homogeneous material. Output consists of joint displacements, reactions, and member forces. The output may be printed at the user's terminal or directed to a file. Graphical output of the results is also available. Keywords: Structural engineering. (sdw)
