Abstract
The computational models used for compression members in the non-linea r linear analysis of space trusses are classified by decreasing order of computational effort into finite, segment, finite-difference, and s ingle-member solutions. The common assumptions and derivations used wi th single-member solutions are reviewed. A chronological re view of th e models is given indicating the contributions each has made. Single-m ember solutions can often give results similar to those that use more computationally demanding methods. However, the success of a model at correlating with experimental behavior depends on the assumptions made . Single-member solutions that include partial plasticity appear more accurate than those that assume full plasticity at midlength. It is ob served that consideration also needs to be given to the relationship b etween the member and the structure to which the member is attached. T hus, internal snap-through or dynamic jump can occur in the postbuckli ng regime of compression members in a relatively compliant adjacent st ructure.
