CAn anyone tell me what the average approx weight of a fully furnished floor of a steel framed skyscraper please.

There's absolutely no way you can just pull numbers out of the air like that. You'd need to find a specific case study.

For instance, one of the two World Trade Centre towers in New York weighed 500,000 tonnes. Dividing this by the 110 floors gets you an average of 4545 tonnes per floor. This includes the steel frame, the cladding, all the dead weights (services) and all the live loads (such as furniture). Taken from: http://www.physforum.com/What-was-th...ower_4299.html

But this is a very clumsy way of doing the calculation. What do you need it for?

...And welcome to the forums

i want to work out the petential energy a building would have. I need to work out the weight of one floor so i can then work out the potential energy of each floor and add them together to get it for all the building

thank you
any change if you know that would be an average for weight for any sky scraper floor?

What kind of energy are you talking about?

Only thing I can think what he means is gravitational potential energy.

You need to define potential to do what?
