1) Specify the dimensions, including thickness of a square base plate for a W150 x 30 column carrying a factored load of Cf = 500 kN. The concrete strength f'c is equal to 20.0 MPa and the yield stress of the steel base plate Fy for base plate is 300 MPa. You may round up the plate dimensions B and C to the nearest 25 mm., and thickness to nearest 5 mm. 2)A beam with a clear span of 12.0 m supports a factored load of 50.0 kN/m. For connection of the beam to each column, two gusset plate are welded to each column flange and bolted to the beam web. The beam web is sandwiched by the gusset plates. At each end, how many 20M grade 8.8 bolts are required. 3) A tension connection. 16M, Grade 8.8 bolts with Fu, bolt = 830 MPa are used. If the tension capacity is governed by shear failure of the bolts, determine the strength of the connection.
