A three-story building has a floor layout as shown in Figure 1 with 30 ft bays in each direction. It must support a uniform dead load of 90 psf and a uniform live load of 80 psf. For LRFD design, determine the required moment and shear strength for beams and required axial strength for columns indicated below. In the calculations, assume all beams and girders are simply supported. a) The beam marked with #1 if the deck spans from line...
