Double-Layer Grids: Review of Static and Thermal Analysis Methods

Abstract

This paper is the first part of a two-part general review paper on static and dynamic analysis methods, and special topics for the design of double-layer grids (DLGs). This work is part of the forthcoming report of the ASCE Task Committee on Double Layer Grids. In this paper, the current state of the art pertaining to the static and thermal analysis techniques (including linear, nonlinear, and stability analyses) of the DLG as a space form as well as components of the system are reviewed with reference to both practical and research tools. A comprehensive reference list is provided, which covers many of the topics related to the analysis of DLGs. The companion paper discusses dynamic analysis methods and other special topics including optimization and probabilistic design considerations. The information provided is useful to both the practicing engineer and the researcher. Some of the topics presented may not be directly applicable to routine design practice, but they are issues that need to be considered as the design and construction capabilities are enhanced.
