What is the difference between thin and thick shell?
Shell problems generally fall into one of two categories: thin shell problems and thick shell problems. Thick shell problems assume that the effects of transverse shear deformation are important to the solution. Thin shell problems, on the other hand, assume that transverse shear deformation is small enough to be neglected. The inclusion of transverse shear…

What is the mechanism for such structures?Are they safe?
We generally see a large portion of Slab is overhanged in different structure. We raise question how such large cantilever is safe? We think really these are cantilever, but actually these are not. Their mechanism is different. See the following picture: The structure is having mechanism of truss system. Slabs, inclined members & columns are…

Advantage of Hollow Section over I Section
The only advantage of hollow section over I section is resistance against torsion. Most of the material is present away from center of mass of the section. To resist torsion we need maximum portion of material away from its center. Take the center of hollow section and draw a line away from its center and…

Types, Reasons & Prevention of Column Failures
We know generally Columns are axially loaded members in structure. It carries compression force due to gravity loads of the structure. Column fails for different reasons. There are mainly three types of failures occur in columns. These are- 1.Compressive Failure 2.Buckling Failure 3.Shear Failure Now let’s discuss about the failure types in details & reason…

All about Burj Khalifa and Reference CAD File of Floor Plans
The Burj Khalifa known as the Burj Dubai prior to its inauguration in 2010, is a skyscraper in Dubai, United Arab Emirates. With a total height of 829.8 m (2,722 ft, just over half a mile) and a roof height (excluding antenna, but including a 244 m spire of 828 m (2,717 ft), the Burj Khalifa has been the tallest structure and building in the world since its topping out in…

Difference between Flat slab and Flat plate slab
Slab directly supported on columns without beams are called Flat slabs or flat plates. 86-Year-Old Bodybuilder Becomes Oldest to Ever Compete in Japan parabolan steroid bodybuilder cedric mcmillan dead at the age of 44 Followings are the difference between Flat slab and Flat plate slab: Serial No. Flat Slab Flat Plate Slab 1 Flat…

Why does required column reinforcement in the upper story appear higher than the lower story? And What are the solutions?
First we need to know about Unbalanced Moment. Unbalanced Moment: Gravity loads on columns consist of an axial load and moments about both axes where the column design moments are caused by unbalanced loading. Such moments are created when there is an imbalance in the loads on one side of the column versus the loads on the…

History of Structural Engineering
Structural engineering dates back to 2700 B.C.E. when the step pyramid for Pharaoh Djoser was built by Imhotep, the first engineer in history known by name. Pyramids were the most common major structures built by ancient civilizations because the structural form of a pyramid is inherently stable and can be almost infinitely scaled (as opposed to…

One Way Slab
One way slab is a slab which is supported by beams on the two opposite sides to carry the load along one direction. The ratio of longer span (l) to shorter span (b) is equal or greater than 2, considered as One way slab because this slab will bend in one direction i.e in the direction along its shorter span. Slabs may be supported on two opposite…

Calculation of Brick Work Quantity: Quantity of Bricks,Quantity of Cement, Quantity of Sand.
We will calculate how to ascertain the quantity of the brickwork required. Here Calculation of Brick Work Quantity nitty gritty clarification given underneath. Subsequent to realizing the 1 meter cube volume we can figure the staying quality effectively by simply increasing the 1 meter cube aftereffect of the ideal volume. 1. The width of the…
