Live load is a civil engineering term for a load that is not constant, but changes over time. Live loads are those loads produced by the use and occupancy of the building or other structure and do not include construction or environmental loads such as wind load, snow load, rain load, earthquake load, flood load, or dead load. The minimum values of live loads to be assumed are given in IS 875 (part 2)-1987. The method of calculating wind loads on structure is given in IS 875 (Part-3):1987. In high rise offices, it is unlikely that all floors . Weight of Steel (2%) in Concrete = 0.18 x 2% x 7850 = 28.26 kg. Live loads are also called as imposed loads. The International Residential Code (IRC) determines the size of your floor joists. Note that some of the engineered-wood-product design software on the market uses the commercial code values.
