Basics of Civil Engineering in Construction

This video talks about the difference between one way and two way slab. It explains when a slab is one way and when it is a two way. It also talks about load transfer mechanism in both one way and two way slab. This video also talks about yield line theory.

This video gives the meaning or definition of the short column effect that is experienced in the buildings. It tells us what is short column effect and in which situations we have short column effect in buildings. It also explains how we can avoid short column effect in buildings.

This video explains the meaning of hidden beams. It also explains when and where these kinds of beams are required in a building construction.

This video describes how torsion in generated in buildings. It also explains what can be done to avoid the torsion in such buildings.

When a building is hit by an earthquake, it is subjected to horizontal force at the floor levels and the whole building is deflected. If the building is regular shaped the deflection is uniform in all the parts of the building. But if it is irregular then the
deflection is not uniform, some parts deflect much and some parts less. Due to this difference in deflection the building as a whole tends to rotate leaving the corners and ends at more stress. This rotation of a building is called the torsion Torsion irregularity shall be considered when floor diaphragms are rigid in their own
plan in relation to the vertical structural elements that resist the lateral forces. Torsion irregularity is considered to exist when the maximum storey drift, computed with design eccentricity, at one end of the structure transverse to axis is more than 1.2
times of the average of the storey drifts at the two ends of the structures.

This video explains the meaning of plinth level. It explains the meaning of the plinth height and the value of the plinth height. It also talks about the DPC or damp proof concrete in buildings.

This video gives the description of the entire procedure of the construction of the isolated footing. This video explains how the work below plinth level is carried out at the site. It shows you the arrangement of the reinforcement of the isolated footing. It also explains the meaning of super structure and sub structure.

This video explains the meaning of lapping of bars. It also explains why we need to lap the bars and the position of lapping for the bars in beam. It also tells us the appropriate lapping length of bars.

This video explains the need of bent up bars in beams and slabs.

This video describes why we add 1.42d for bent up bars while calculating the total length of the bar.

This video describes the lapping of bars in the column. It explains why we need to lap the bars. This video explains the proper position for the lapping of bars in the column. The lapping position is as per IS 13920:2002. It also talks about the ductility detailing of column.

This video explains the meaning the grade of concrete. It explains how the grade of concrete is specified. It explains what is the meaning of the M20 or any grade of concrete.

This video talks about the constituents of the concrete,. It explains the meaning of characteristic strength and target mean strength of the concrete. It explains bell shaped curve of the compressive strength test results of the concrete.
