In this analysis & design of Gantry Structure for Switchyard loading & analysis is govern for dead, live, Wind & Electrical loads i.e. Normal Condition and Short circuit condition load as per different location, height, size of Tower structure & Capacity of Overhead cables in kV. Generally whole structures design as a conventional sections like angle, etc. Main reason is whole structural members sections are all sections locally available, easy to construct, transport & economical. Here, involves all study to resolves & enhance more efficiency of structures. Trying to design Structure economically by selecting proper Bracing system. In order to properly plan and design a structure, it is necessary to have not only imagination and conceptual thinking, but also a solid understanding of the science of structural engineering, as well as practical knowledge of recent design codes and regulations, all supported by ample experience, intuition, and judgment, with the goal of ensuring safety while maintaining a careful balance between economy and safety.
