The plan view below is for a two story building with a height of 15 ft. per floor. The first floor live load is 40 psf and the roof live load of 25 psf. A. Calculate the reduced live load at column B due to floor loads and due to roof loads. B. Calculate the change of length in column B as a result of temperature decrease of 70°F (Concrete coefficient of thermal expansion = 0.000006 in/in/"F) – Do you expect any residual stresses build-up as a result of temperature change?
