Hi,
I already have a 3 year old house with basement + 3 floors. Structure was designed with a structural engineer consultation. There are 12 pillars in the 30X40 area. Each pillar is 18 X 9 inches. each pillar has mix of 16mm & 12mm rods.
I am covering the terrace with roof tiles supported by steel structure (kind of addtional floor without walls). I have steel pipes with base plate planted to the pillars and roof tiles placed on this structure. this additional structure will add around 15 tonnes - 4 tonne steel (column, rafters, perlines) & 10 tonnes of double layer tiles.
My question is, will the current structure with the above specified pillars take this additional 15 tonnes without any problem?
Thanks,
Raj
