Double-Layer Grids: Review of Dynamic Analysis Methods and Special Topics

Abstract

This is the second part of a two-part paper on the general review of static, dynamic, and thermal analysis methods, and special topics for the design of double-layer grids (DLG). This work forms part of the anticipated report of the ASCE Task Committee on Double Layer Grids. In this paper the current state-of-the-art information pertaining to the dynamic analysis techniques and special topics for the DLG structural system are reviewed with references to both practical and research tools for analysis. A comprehensive reference list is provided, which covers many conventional and emerging topics related to the analysis of DLGs. Topics presented include dynamic linear, nonlinear and stability analyses, dynamic loadings, progressive collapse, dynamic effects of member failure, optimization techniques, probabilistic methods, vibration control, system identification and damage detection, special application DLGs, and other newly emerging analysis methods. The first paper dealt with static and thermal analysis and member behavior. The information presented in this paper is useful to the practicing engineer and for research. Some of the information though not directly applicable in routine design, may have to be considered for special cases and as the design and construction capabilities of DLGs are enhanced.
