This report provides guidelines for the design of double-layer grids, a type of space frame. Space frames are three-dimensional, lattice-type structures that provide great rigidity and inherent redundancy. Space frames are one of the more efficient uses of structural materials, and they satisfy demand for large column-free areas. The most common example of a space frame is the double-layer grid, which consists of two parallel layers of top and bottom cords interconnected by inclined and/or vertical web members.

This report provides an overview of double-layer grids and discusses their structural behavior. Various methods to analyze these structures?including static analysis, dynamic analysis, thermal analysis, and optimization analysis?are explored. This guide concludes with experimental studies involving double-layer grids and implications for design.
