The purpose of this book is to enable engineers to learn the concepts of shear stress, shear deflection, and shear center. Familiarize with the theory behind struts (columns) and parameters involved in their design and analysis of statically indeterminate beams and structures. Also, engineering students can find this book useful in solving problems relating to columns and be able to design the same, analyze and design complex structures which are statically indeterminate and lastly acquire knowledge on the design of simple plates and cells from a structural perspective.
