Hello all . I would like to present to you in this topic a book about Design of Electrical Transmission Lines Structures and Foundations by Sriram Kalaga and Prasad Yenumula
About this book :
This ebook covers structural and basis techniques utilized in high-voltage transmission strains, conductors, insulators, {hardware} and element meeting. In most growing nations, the time period “transmission buildings” normally means lattice metal towers. The time period really features a huge vary of structural techniques and configurations of assorted supplies resembling wooden, metal, concrete and composites. This ebook discusses these techniques together with related subjects resembling construction capabilities and configurations, load instances for design, evaluation methods, construction and basis modeling, design deliverables and newest advances within the area. Within the foundations part, theories associated to direct embedment, drilled shaf ts, unfold foundations and anchors are mentioned intimately.
That includes labored out design issues for college kids, the ebook is geared toward college students, practising engineers, researchers and teachers. It incorporates useful info for these concerned within the design and upkeep of transmission line buildings and foundations. For these in academia, it is going to be an ample text-book / design information for graduate-level programs on the subject. Engineers and managers at utilities and electrical firms will discover the ebook a helpful reference at work.

This book covers structural and foundation systems used in high-voltage transmission lines, conductors, insulators, hardware and component assembly. In most developing countries, the term “transmission structures” usually means lattice steel towers. The term actually includes a vast range of structural systems and configurations of various materials such as wood, steel, concrete and composites. This book discusses those systems along with associated topics such as structure functions and configurations, load cases for design, analysis techniques, structure and foundation modeling, design deliverables and latest advances in the field. In the foundations section, theories related to direct embedment, drilled shaf ts, spread foundations and anchors are discussed in detail.
Featuring worked out design problems for students, the book is aimed at students, practicing engineers, researchers and academics. It contains beneficial information for those involved in the design and maintenance of transmission line structures and foundations. For those in academia, it will be an adequate text-book / design guide for graduate-level courses on the topic. Engineers and managers at utilities and electrical corporations will find the book a useful reference at work.
