Types Of Loads On R.C.C Structures

Types Of Loads On R.C.C Structures :-   

      

           Structures are designed to withstand various type of loads. The various type of loads expected on a structure are as follows:

• Dead Load :- 

          

Dead, live and wind loads

             The unit weights of commonly used building materials are given in the code IS 875 (part-1)-1987

• Live Loads :- 

               Live loads on floors and roofs consists of all the loads which are temporarily placed on the structure, for example, loads of people, furniture, machines, etc. These loads keep on changing from time to time. They are also called as imposed loads. Various types of imposed loads coming on the structure are given in IS 875 (Part-2): 1987. The imposed loads depend upon the use of building.

• Wind Loads :-

            The force exerted by the horizontal components of wind is to be considered in the design of building. It depends upon the velocity of wind, shape and size of the building. The method of calculating wind load on structure is given in IS : 875 (Part-3) 1987. It is also called as Lateral Loads.

• Snow Loads :-

             The building which are located in  the regions where snowfall is very common, are to be designed for snow load. The code IS : 875 (part-4) 1987 deals with snow load on roofs of the building.

• Earthquake Loads :- 

           Earthquake loads depend upon the place where the building is located. As per IS : 1893-2002 (Part-1), India is divided into four seismic zones. The code gives recommendations for design of structures. It is also called as Lateral Loads.
