Guidelines for the Design of Double Layer Grids (Hardcover)

Representing one of the more efficient uses of structural materials, space frames are three-dimensional lattice-type structures that provide great rigidity and inherent redundancy. With the need for large column-free areas, the space frame design has become more popular. The most common example of a space frame is the double-layer grid (DLG), which consists of two parallel layers of top and bottom cords interconnected by inclined and/or vertical web members. This book provides guidelines for the design of double-layer grids. It begins with an overview of DLGs and a discussion of their structural behaviour. Next, the various methods used to analyze these structures are explored. Some of the methods included are: static analysis, dynamic analysis, thermal analysis, and optimization analysis. Finally, this guide presents experimental studies involving double-layer grids and their implications for design.
