Load Factors for Live and Dead Load in Civil Engineering
In the design of structures, it is important to consider the loads that the structure will be subjected to. The loads can be classified as live loads and dead loads. Live loads are the loads that are temporary and can change in magnitude and location, whereas dead loads are the loads that are permanent and remain constant throughout the life of the structure. Load factors are used to account for uncertainties and variations in the loads that the structure will be subjected to.
Load factors for live and dead load are taken respectively as 2.2 and 1.5 in civil engineering. Let's understand why it is so.
Load Factor for Dead Load
Dead load is the weight of the structure itself, including all permanent fixtures and finishes. The weight of the structure is known with reasonable accuracy, and it is a constant value. However, there may be uncertainties in the weight of finishes and fixtures. Therefore, a load factor of 1.5 is used for dead load to account for these uncertainties.
Load Factor for Live Load
Live loads are the loads that are temporary and can change in magnitude and location. Examples of live loads include people, furniture, vehicles, and equipment. The magnitude and location of live loads are uncertain, and they can vary widely. Therefore, a load factor of 2.2 is used for live load to account for these uncertainties.
Conclusion
In conclusion, load factors are used in civil engineering to account for uncertainties and variations in the loads that the structure will be subjected to. Load factors for live and dead load are taken respectively as 2.2 and 1.5. A load factor of 1.5 is used for dead load to account for uncertainties in the weight of finishes and fixtures, whereas a load factor of 2.2 is used for live load to account for uncertainties in the magnitude and location of the load.
