A) Determine the shape factor and the Fully Plastic Moment (Mp) for the shaded symmetrical hollow rectangular beam section shown below. Assume the yield stress Oy =275 N/mm². B) If two plates of width 250 mm and thickness equal to 't' mm is connected (fabricated) at top and bottom (one plate on each side) for the given section, then what is the improvement in the fully plastic moment(Mp) of the section. C) If this revised fabricated section is now rotated by 90 degrees, what is its effect on the shape factor of the section? 200 mm. 50 m 100 ma 400 t- 10mm Note Take the value the 't' as equal to the last two digits of your studentid. If the last two digits are zero then take timm
The rigid frame shown in Figure is unbraced. The members are oriented so that bending is about the strong axis. Support conditions in the direction perpendicular to the plane of the frame are such that Ky = 1.0. The beams are W18 x 50, and the columns are W12 x 72. A992 steel is used. The axial compressive dead load is 50 kips, and the axial compressive live load is 150 kips. a. Determine the axial compressive design strength of column AB. Use the stiffness reduction factor if applicable. b. Determine the allowable axial compressive strength of column AB. Use the stiffness reduction factor if applicable.
