19 31000 46 ST12x50 Q3: Determine the critical buckling load, the design and the allowab unbraced frame using 2 MC18x58 through specified equation and AISC Tables, compressive and tensile strength and load of the column (AB) of 18ft in the k-factor from Question 3. Also, determine the critical stress on the maximum the proportional limit of the steel is 50ksi and the ultimate stress is 60ksi. Use the distance that is required to tie and fix the double MC18x58. Elasticity modulus slenderness ratio of column. Suggest the tie plate dimensions, thickness, and is 28,000ksi. The double MC-section is used as in the following manner.
