Problem Set No. 2 The supported edges of Panels 1 and 2 in the floor system shown may be considered fixed inasmuch as these are monolithic with their supporting beams. At all the supports, top bars, 12 mm dia bars spaced at 125 mm o.c are placed perpendicular to the beams. The bottom of the slabs have been provided with 12 mm dia bars spaced at 200 in the short direction while 250 mm o.c in the long direction. The slabs are 140 mm thick. Assume that the centroid of short direction bars is 30 from the face of concrete under tension while those in the long direction, 42 mm. fc' = 28 MPa, fy = 275 MPa 1. Locate the critical yield line pattern (failure mechanism) for Panel 1 2. Determine the magnitude of the largest uniform load Wu, in kPa, that Panel 1 can safely sustain. 3.
