Method of Analysis
Publication: Substation Structure Design Guide: Recommended Practice for Design and Use
Abstract
The design of substation structures requires knowledge of the equipment being supported by the structure, its operation, and electrical and safety codes. The analysis of a structure begins by developing a model of the structural configuration, connection characteristics, support boundary conditions, material properties, and loading cases. An analysis of a structure generates both stresses and deflections, which may be used to determine the adequacy of the structure. The analysis model is a set of mathematical equations to predict the behavior of the structure. In developing a model of a structure, assumptions are made concerning the individual elements, their geometrical and mechanical properties, and the connections, loads, and foundation supports. These are discussed in this chapter. A static analysis may be used for the seismic design of rigid structures in substations. Performing a dynamic analysis requires a thorough understanding of the background material.
