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…

Strong Axis Weak Axis.
Every structural member has its strong as well as weak axis. A beam will fail easily along the direction of lower moment of inertia, a column will fail about the axis with lower radius of gyration. So the big question is how to find a strong or weak axis for the given cross section. Now…

What is Pile Foundation? Types of Pile Foundation.
Foundations provide support to the structure, transfers the loads from the structure to the soil. But the layer at which the foundation transfers the load shall have an adequate bearing capacity and suitable settlement characteristics. There are several types of foundation depending on various considerations such as- Total load from the superstructure. Soil conditions. Water…

What is Prefabrication and how Prefabrication can help build Emergency Buildings?
What is Prefabrication?The manufacture of elements of a building off-site before being installed onsite is prefabrication. How is it different from the conventional construction?Unlike the traditional process, where each process is dependent upon the next, prefabrication can create concurrency, resulting in cost precision and schedule reductions. Does prefabrication require a different estimation approach?The best approach…

Bar Bending Schedule (BBS) and Its Advantages
Preparation of Bar Bending Schedule (BBS) Bar bending schedule or schedule of bars (BBS) is a list of reinforcement bars for a given reinforced concrete work item, and is presented in a tabular form for easy visual reference.Table of bar bending schedule summarizes all the needed particulars of bars – diameter, shape of bending, length…
