Structural Engineering BTech structural engineering is a broad specialization of civil engineering, structural engineering is all about analyzing, planning, designing and overlooking the construction of large structures like bridges, tunnels, buildings, flyovers etc.  It is a 4 year undergraduate course where students learn the basic principles of structural analysis which involves examining the strength, stability and durability of structures. This course is a sub-discipline of civil engineering in which structural engineers are trained to design the 'bones and muscles' that create the form and shape of man-made structures. It involves the
