As per IRC 6 - 2017, Note Below Table B.3 Page 95, Note No. 3 "Wind load and Thermal load need not be taken simultaneously unless otherwise required to cater for local climatic condition".

Now, the question is, Where in India such condition will occur, when we need to consider both Thermal and Wind simultaneously for Bridge superstructure or for any structure?

The table mentioned above is for Partial safety factors for verification of serviceability Limit State.

Dear Er Jalgaonkar,

This is a place where the engineer has to use his/ her own judgement. In my opinion, desert areas can have very high wind speeds at the same time as positive thermal gradient, while mountain areas in the Himalayas can have high wind speeds and positive/ negative thermal gradient at the same time.
