For the slab shown in the figure, Fy= 420 Mpa, Col. Dimensions = 400 x 400 mm, check slab thickness at exterior panel for deflection control for the following cases: 1- Flat slab without edge beam and without drop panel 2- Use edge beam only. 3- Use Drop Panel only. 4- Use edge beam and drop panel. 5- Use beams for all lines with am=0.5. 6- Use beams for all lines with am = 1.5. 7- Use beams for all lines with um= 2.5. Discuss the results. 7.2 m 7.2 m 7.2m 7.2 m 7.2 m 7.2 m

SOLVE THIS PROBLEM USING THE SLOPE DEFLECTION EQUATIONS: The bearing type connection show is bolted by 4 – 22 mm diameter bolts (high strength bolts). The size of the plates is 300 mm x 12 mm. Fy 248 MPa, Fn = 330 MPa and Fu = 400 MPa. Determine the following: (1) Design strength of the connection based on strength of plates. (2) Design strength of the connection based on shear strength of bolts. =0.65. (3) Design strength of connection based on bearing strength of bolts on the 12 mm plate. =0.75 12 mm P. mm O.
