A fivestory building has the elevation shown below. The building has typical column grids at on center in both orthogonal directions. The floor dead load is and the live load is The roof dead load is with a flat roof snow load of In order to span over a large atrium area at the ground floor, a series of transfer plate girders spanning and spaced at on center are to be used at the secondfloor level. Neglect any live load reduction and ignore diagonal tension field action. Assume grade steel and that the compression flange is fully braced.
a Calculate the maximum moment and for a typical interior secondfloor transfer plate girder to support the column loads from above as well as the second floor.
b Perform initial sizing of the interior plate girder based on the Moments and Shears calculated in part a above and :
