The Lighting Technique is different for different purposes….

For example: Dining Lighting Techniques are different from Underwater Lighting Techniques… The kind of lights used in the Underwater Lighting system are different from that of the lights used in Dining Lighting and for specific purpose such as Task Lighting.

The material of the lights used for lighting varies for the type of ambiance it is supposed to create. The material of the underwater lights is different from the material of the other lights used for other purposes.

In this article we are going to discuss different types of Spotlights and situations where it is used.

New Changing trends in the Materials and Furniture design | Interior Design

Changing trends in the choice of Building materials

Nowadays, people are gaining more knowledge about eco-friendly lifestyle. They are realizing that eco-friendly materials are much better and safer as compared to the synthetic and energy intensive materials. Though use of synthetic materials give a very stylish and trendy look to the place, they are not eco-friendly. The trend is definitely away from the older classical looks, associated with bygone grandeur and towards more contemporary styling. Fabric is more textured and interesting, with graphics, florals and interesting weaves and patterns to the fore.

The palette is lighter and brighter than before, in keeping with the move away from the traditonal to the contemporary, also following what is seen as international, stylish and sophisticated. Instead of saying ‘the look has changed’, I would rather say the look and feel of traditional interiors has evolved. New design languages generated by new materials and new uses of existing materials have resulted in a truly matured genre of beautiful and amazing interiors.

Consequences of Wrong Structural Design | RCC Structures

A lesson for all the Civil Engineers and Designers to learn

I got a project of designing (Architectural Design) a Hostel in Lucknow, India. The Structural design that is, column positions and wall construction was already done. The client wanted me to design a Hostel keeping the column positions and exterior wall construction intact. I have written this article to address all the Civil engineering students as well as Civil Engineers to avoid making such blunders while they design. Please do read this article because understanding the intensity of the job of a Civil Engineer is must for every student and professional. I guess this realization has been washed away and forgotten in the wave of commercialism.

Hostel Design, Lucknow, India

The client mailed me the layout of the existing construction. After I studied the layout, I figured out that the Column layout was pathetic. I wonder what kind of Civil Engineer must have made the layout or if at all any Civil Engineer has done it.

Errors in Construction

Wrong size of the Columns

The size of the columns was 9”x9” and the building is supposed to be constructed upto G+2 floors which is really disastrous for the structure.

It could lead to structural failure and ultimately structural collapse.

(The duty of the Civil Engineer is to understand and not make such dramatic blunders. The consequences of this kind of structural design could be disastrous.)

Column layout and Exterior wall Construction
Column layout and Exterior wall Construction

9”x9” size columns are only preferred if you were to construct only a ground floor structure using M15 grade concrete. If you are to construct another floor that is (G+1), the minimum size of the column should not be less than 9”x12” using M15 grade concrete.

If the client insists on using smaller columns (9”x9”); in that case, use of M20 grade concrete should be done mandatorily and the construction should not be initiated before the client agrees to do so.

Growing Need for Environmental Sustainability

Chronic Need for Environmental Sustainability

Everyone is aware of the fact that the life on earth is degrading day by day. The quality of life on earth has gone from best to worst in the past 150 years.

For people who do not agree with the concept of Sustainability

The concept of sustainability is brought up for the betterment of human species and not for the earth. The Earth can survive without humans. Sustainability is for us to survive on earth.

The video illustrates the story of our Mother Earth or rather I should say “Sad story of Earth”….

Earth was beautiful and Green before humans started using Earth’s resources ruthlessly… The earth is now in the devastated condition and if this continues for the next 50 years, it will bring with it the end of Human life on Earth by the next century.

We should all work towards making our environment green and sustainable because we are the ones who are responsible for getting it into such a bad ruined state.

Guide to Design of Built-up Beams

Design Procedure of the Built-up Beams design

In my earlier articles, we discussed in detail about the “Theory of Built-up Beams“. In this article, we will move a step ahead and understand the concept of the design of Built-up beams.

Here are the simple steps that are to be followed for the design of Built-up Beams.

Step one

The effective span and load required to be carried by the built-up beam are known.

Maximum bending moment and shear force in built-up beams are calculated.

Step two

Value of yield stress (fy) for structural steel is to be assumed.

The permissible bending stress (sigma bc) is calculated.

Step three

The required section modulus (Z) for the given beam section is calculated.
