Is 875 wind load a map?

THE wind speed map included in the IS:875 (Part-3)1, serves the primary purpose of choosing the appropriate basic wind velocity for the design of buildings and struc- tures. The cur- rently used design wind speeds are based on their return period at different locations.

What is the live load of a floor?

The live load is the weight of furnishings, people and anything else that the floor needs to support, but which isn’t permanently attached. The dead load on a floor is determined by the materials used in the floor’s construction.
