#### 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
- Loads on Beams
- Loads on slabs

#### 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
