## Parallel processing for transient nonlinear structural dynamics of three-dimensional framed structures

A variety of strategies are developed for the practical solution of the fully nonlinear transient structural dynamics problem in a coarse-grained parallel-processing environment. Emphasis is placed on the analysis of three-dimensional framed structures subjected to arbitrary dynamic loading and, in particular, steel-building frames subject to earthquake loading. The parallel algorithms developed and investigated are intended to be appropriate for finite-element models that uses structural elements (e.g., beam-columns). Explicit algorithms require no simultaneous solution of equations, employ simple communication, and are thus efficient for parallel processing. Parallel analysis using the central difference algorithm is examined and implemented. The strict stability limitmore »
