Question

: In the flooring system shown below, cold-formed 103 x 68 x 2.6 RHS (non-stress relieved, fy = 422 MPa and E = 200 GPa) are used as piers to support the loads from the bearers. Assume one of the piers has a height of 1.96 m and is pin-connected at the top and fixed at the bottom. The cross-sectional area of the pier can be calculated from the section dimensions by ignoring the rounded corners. Determine the following: The effective cross-sectional area Ae of the pier (3 mark) (Unit: mm2) The section compressive capacity of the pier (1 mark) (Unit: kN) The member slenderness reduction factor of the pier (2 marks) (Unit: ) The member compressive capacity of the pier (1 marks) (Unit: kN) The theoretical elastic buckling load of the pier (3 marks) (Unit: kN)

Answer 1

Good Evening Sir/Madam,

Please follow the attachments produced below!!

i think in the problem, sectional details are missing...!!with out that that we can't move further....but I tried to find out 2 more questions that are mentioned...!!!
