When you are planning your project it will become very important for you to be able to learn how to calculate the number of bricks in your wall. It is quite simple how to work out the number of bricks you will require, but there are a few considerations you must consider: • Thickness of […]

What is Stirrup ? A reinforcement used to resist shear and diagonal tension stresses in a concrete structural member. Or The term stirrups is usually applied to lateral reinforcement in flexural members and the term ties to lateral reinforcement in vertical compression members. In uniaxial compression test of concrete, upon reaching the ultimate load failure […]

This construction video provides detailed guidelines on foundation marking. In the video, the plan of building is given for living room and kitchen room. The center line marking is also provided with 6 numbers of columns. Initially, you have to set the base point as it is very crucial for marking. After that, a base […]

The moment of inertia, otherwise known as the angular mass or rotational inertia, of a rigid body is a tensor that determines the torque needed for a desired angular acceleration about a rotational axis. It depends on the body’s mass distribution and the axis chosen, with larger moments requiring more torque to change the body’s […]

By going through the following construction video, you can learn the tips for obtaining formula toward full super elevation of highway or road. This video is very useful for land surveying. Full super-elevation stands for the amount with which the external edge of a curve located at a road or railway is grounded directly above […]

First, assess the size of the area that you’re painting. Grab a friend to help measure the width and height of walls with a metal tape measure and multiply these together to calculate the overall square metre measurement. Subtract the space used by windows and doors using the same calculation method as above, and remove […]

In order to calculate the volume of any cement bag, We need to know the density of cement bag. The unit weight of the bag is 50 kgs Density of cement in loose condition is 1440 kgs/m3 Density = mass/volume (ρ=m/V) So, V=m/ρ 50 kg ÷ 1440 kg/m3 = 0.0347 m3 = 1.23 CFT   […]

ONE – WAY SLAB One – way slabs are those slabs with an aspect ratio in plan of 2:1 or greater, in which bending is primarily about the long axis so, the slab is one way where L/B>=2 Types of one way slab One way slab may be… 1) Solid 2) Hollow 3) Ribbed   […]

You just need to visualize the dimensions (Length, Breadth, Depth) of the structural member (Be it a beam, slab, column or a footing) and then you need to visualize the shapes of bars that needs to be used followed by some simple calculations. Here is a very informative video by SL Khan about Steel Calculation […]

To calculate the quantity of steel spirals ( or spiral ties) in steel cage (or sometimes rebar cage) for piles ( reinforced concrete or bored pile), you have to have the following informations ( check the details in the drawings) : a) diameter of pile b) length of pile c) pitch of spirals (spacing of […]
