Nonlinear Dynamics: An Intuitive Digital Representation of Structure

Abstract

The article discusses the pedagogic advantages of structural analysis software based on nonlinear dynamic structural theory, in contrast to software most commonly used in architectural education which is based in linear static theory. Traditionally, structural education in both architecture and engineering has considered nonlinear dynamic theory to be an advanced-level tool, reserved for graduate level engineering study. The article illustrates that with an appropriate interactive interface, nonlinear dynamics can support on-screen structural models that are far more physically intuitive. The article includes examples of student work from a first course in structural design.

Keywords:
