We have recently proposed a design for a G+1.5 house on a plot size of 45′ x 37′ 6″. The ground floor has a large living room, one guest bedroom, kitchen and dining room. We also have a combined store + washing machine room. The staircase is 3′ 6″ wide. Slab top per floor is 12′ 3″, with a total of 21 steps of 7″ height each.
In my earlier article, we discussed three important thumb rules that are to be followed while making a column layout for any building. They are as follows:
In this article, we will see an example of a residence of which column layout is done keeping the above three thumb rules in mind.
The residential villa comprises of 1 and half floors. Initially, the column size 9″x12″ had been used with the use of M15 grade of concrete. The builder wanted to save on his budget by making the columns smaller in size. That is why, the columns in the Floor plans below are 9″x9″ in size but the Engineer made sure that M20 grade of concrete would be used for Columns.
A building is composed of various structural components such as Foundations, Plinth beams, Columns, Beams, Slab, Staircase, Doors and Windows.
Foundation design is the structural component from where the RCC design is initiated. The foundation design guide discussed earlier includes in detail the design procedure for isolated column footing. Column footing is the most commonly used type of foundation. It serves a variety of different buildings.
Beams are mainly classified into two types:
The article discusses the classification criteria for a column, and design of different types of reinforcements for columns which include longitudinal, transverse and helical reinforcements.
