Is 875 a wind zone?

IS-875 is the standard in India for design loads (other than earthquake) for buildings and structures. Basic wind speed as applicable to 10 m height above mean ground level for different zones in the country can be directly calculated if the proper value is defined in the Wind Zone Number box.

IS 875 (Part-II)-1987 specifies the live loads for following occupancy conditions: Residential Buildings- dwelling houses, hotels, hostels, boiler rooms and plant rooms, garages etc. Educational buildings.

Is code for wind design?

Section 2 of this volume contains illustrative examples designed to demonstrate the various parts of the —Indian Standard I.S.: 875 (Part 3)-1987“ dealing with wind loads on buildings and structures.

Is 875 explanatory handbook?

875 (Part 3) œ Wind Loads on Buildings and Structure- draft revision. This work has been supported through a project entitled Review of Building Codes and Preparation of Commentary and Handbooks awarded to IIT Kanpur by the Gujarat State Disaster Management Authority (GSDMA), Gandhinagar through World Bank finances.

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.

Is 875 wind load calculation?

Calculate Basic Wind Speed, V b, based on mapped values (Figure 1 in Section 5) or the table supplied in Appendix A of IS 875. Calculate Probability Factor (risk coefficient), k 1, from Table 1 in Section 5 of IS 875. Calculate the Topography Factor, k 3 per Appendix C in IS 875. …

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.

Are clauses related to load from 875 1987?

It included the provisions for the basic design loads ( dead loads, live loads, wind loads and seismic loads ) to be assumed in the design of the buildings. Earthquake load is covered in a separate standard, namely, IS : 1893-1984* which should be considered along with the above loads.
