However, in a multistoried buildings chances of full imposed loads acting simultaneously on all floors is very rare. Some of the important values are presented in table below which are the minimum values and wherever necessary more than these values are to be assumed. Since it is unlikely that any one particular time all floors will not be simultaneously carrying maximum loading, the code permits some reduction in imposed loads in designing columns, load-bearing walls, piers supports and foundations. The floor slabs have to be designed to carry either uniformly distributed loads or concentrated loads whichever produce greater stresses in the part under consideration. The code gives uniformly distributed load as well as concentrated loads. Residential buildings–dwelling houses, hotels, hostels, boiler rooms and plant rooms, garages.The code gives the values of live loads for the following occupancy classification: It depends upon the intended use of the building. The minimum values of live loads to be assumed are given in IS 875 (part 2)–1987. It is one of the major load in the design. These loads are to be suitably assumed by the designer.

Live loads keeps on changing from time to time. These loads are assumed to be produced by the intended use or occupancy of the building including weights of movable partitions or furniture etc. Live loads are either movable or moving loads with out any acceleration or impact. The second vertical load that is considered in design of a structure is imposed loads or live loads. Read: Unit Weight / Density of Different Construction Materials 2. Unit weights of some of the common materials are presented in table below. The calculation of dead loads of each structure are calculated by the volume of each section and multiplied with the unit weight. which are otherwise the permanent parts of the building. It majorly consists of the weight of roofs, beams, walls and column etc. Dead load is primarily due to self weight of structural members, permanent partition walls, fixed permanent equipments and weight of different materials. Dead loads are permanent or stationary loads which are transferred to structure throughout the life span. The first vertical load that is considered is dead load. Types of loads acting on a structure are: Indian standard code IS: 875–1987 and American Standard Code ASCE 7: Minimum Design Loads for Buildings and Other Structures specifies various design loads for buildings and structures. So the estimation of various loads acting is to calculated precisely.

If economy is considered and loads are taken lesser then the safety is compromised.

If the loads are adjudged and taken higher then economy is affected. In a construction of building two major factors considered are safety and economy. Types of Loads on Structures and Buildings Other Loads and Effects acting on Structures Types of Loads on Structures and Buildings.
