## Understanding Load Calculations | Structural Design

#### Load Calculations | Design of Buildings

In our earlier article, we discussed “Different types of loads” and their importance in Structural design.

#### Now we will move on with our further discussion on the following points:

• Design principle assumption and notation assumed
• Design Constant
• Assumptions regarding Design

#### Design principle assumption and notation assumed:

The notations adopted throughout are same as given in IS:456:2000

Density of material used in accordance with reference to IS:857-1987s

 Sr.no Material Density 1 Plain concrete 24 KN/m3 2 Reinforced cement concrete 25 KN/m3 3 Flooring material (cement mortar) 1.00 KN/m3 4 Brick masonry 19 KN/m3

#### Design constant

Using M20 and Fe415 grade of concrete and steel respectively for columns and footings

Therefore:

Fck – i. e. Characteristic strength for M15 – 15 N/mm2

Fck – i. e. Characteristic strength for M15 – 15 N/mm2

Fck – i. e. Characteristic strength for M20 – 20 N/mm2

Fy – i. e. Characteristic strength for steel – 415 N/mm2

## Introduction to the calculation of the loads | Building Construction

Students find it difficult to understand the concept of loads although it is a very simple concept. We are going to write a series of articles on “Load Calculations” and help you all in understanding different types of loads that are to be considered for structural designing and also how to calculate them.

#### An object is subject to mainly two types of forces:

Basically, an object subject to any type of force which could be gravitational force (weight), pressure or anything affects the object is called a load.

This concept is used in Mechanical and structural engineering. Let’s take in terms of Structural Engineering. Whenever a structure is designed, these concepts are taken into consideration because real world objects are analyzed in order to design the structure. This is very important in terms of structural stability.
