Hi,
I am designing a concrete pad foundation 1m x 1m x 250mm thick. The column (6.2m long) is centrally loaded onto the foundation with a total axial load from roof (SLS) of 27kN. Wind load acting on column/walls which the foundation takes is approx 20kN.
I am aware that the load combination used is 1.4Wk + 1.0Gk but I am unsure how to check if the foundation is adequate!
Do i work out a moment induced from the wind on the column into the foundation and check if the design moment of the foundation is greater than this.... or is there a different way of working this out like checking self weight of foundation is greater than 1.0Gk +1.4Wk?
Thanks
