A square steel slab base of are 1 m2 is provided for a column made of two rolled channel sections. The 300 mm 300 mm column carries an axial compressive load of 2000 kN. The line of action of the load passed through the centroid of the column section as well as of the slab base. The permissible bending stress in the slab base is 185 MPa. The required minimum thickness of the slab base is
A strut in a steel truss is composed of two equal angles ISA 150 mm 150 mm of thickness 100 mm connected back-toback to the same side of a gusset plate. The cross sectional area of each angle is 2921 mm2 and moment of inertia (Ixx = Iyy) is 6335000 mm4 . The distance of the centroid of the angle from its surface (Cx = Cy) is 40.8 mm. The minimum radius of gyration of the sturt is
