Shear Lag in Steel Structures

If we consider ourselves attending a design class in the undergraduate degree program, once the design philosophies are over, the first design lecture would be on “Design of Tension Members”. Have you ever wondered, why we are learning this thing…

Lateral Torsional Buckling

What happens to a member, when it is subjected to transverse loading? A member subjected to transverse loading will undergo bending and start to deflect along the plane in which it is loaded. It seems so simple, right?    Now,…

P-Delta Effect on Structures

P-Delta Analysis is a Non-linear second-order analysis which exhibits a considerable increase in the base moment when a structure is subjected to large lateral displacement due to wind or seismic forces. Before moving further, there are two terms that need…

Why “Prying Force” is important?

Our previous post is about structural steel connections, emphasizing its importance and complexity. This post is sort of continuation of the previous post, which is going to emphasize on the additional tension force that is developed in the bolted connections…

Why web takes all the shear in an I- section?

During the initial stage of one’s career, every design engineer, especially a steel design engineer would have come across this statement “Bending force is carried by the flange of an I-Section, and shear force is taken care of by the…
