Abstract

Large structural projects, such as lattices for framing tall buildings or space purpose can result in huge finite element models. The use of continuum methodology for conducting both linear and nonlinear analyses of lattice structures in finite-element models results in significantly fewer degrees of freedom than discrete finite-element models, which individually model each structural element. Hence, the use of continuum models can result in a considerable reduction in computational effort with a corresponding savings in cost, at least during early 1990s when Pentium computer was not available. Now, it can still be a good design method especially for tall buildings in the preliminary stages of structural design because through the displacements under the axial, shear and moments stresses on the continuum model, the sizes and shapes of members can be determined for the structural system. Besides, it is also useful to check the results obtained from a commercially available computer structural program.
