Abstract : The analysis of complicated structural systems with both linear and nonlinear components by a conventional direct time-history integration of the equations of motion presents a formidable computational problem. The nonlinear force-displacement behavior, commonly known as material or constitutive-type nonlinearity, of one or more of the structural components may necessitate the reformulation as well as the solution of the system equations of motion at each time step. For many practical structures, the computational effort required is often too great to facilitate an economical solution. Clearly, a more efficient procedure would be of value. In this work, one such method is presented, as well as the results of an investigation of its use in solving a typical problem in the analysis of particular class of structural systems.
