AN interactive, menu-driven computer program, SOLVER, for analyzing 2- or 3-dimensional skeletal structures such as continuous beams, trusses, frames and grids, was developed for use on microcomputers. Using the direct stiffness method in conjunction with recommendations of the 1982 National Design Specification of Wood Construction, the program determines stresses, node displacements, reactions, member deflections and combined stress interaction analysis of wood trusses and frames. The program offers several options for the analysis of member capacity as affected by strength property variations, loads, and joint fixity conditions. Options for tabulated output range from a summary report of structural response to detailed information of member forces, stresses, deflections and computational results from key steps in matrix structural analysis.
