Abstract
There is no doubt that every space frame structure is under some degree of direct member loading. At least, the self weight of the structure certainly affects the members directly, and in structures covered with cladding panels or have top concrete slabs, their weight is also likely to apply some lateral pressure on the members. In spite of this fact, direct member loading is usually ignored in space frame designs and assumed to lead only to a negligible effect on frame performance. This study is intended to explore this point and identify the actual effects that can arise from direct member loading, and eventually provide an answer to the question of whether the current design practice is satisfactory or certain modifications are needed. After presenting a new analytical technique to allow the accurate analysis of space frames with laterally loaded members, a wide parametric study involving practical-size space frames with different configurations, aspect ratios, boundary conditions, numbers of chord panels and degrees of curvature, is described.
