Question: AISC 360-16 An American National Standard (Specification for Structural American Steel Buildings) (If you don't know this regulation, you can do it using staggered (While finding the An)) UPN 280

Question: Use AISC 360-16, LRFD throughout. 1. Determine the LRFD design moment strength in kip*ft of a W21x50 of A992 having the compression flange fully braced. Bending is about the strong axis (x-axis).ΦMnx = 2. Determine the LRFD design moment strength in kip*ft of a W21x50 of A992 having an unbraced length Lb = 6 feet and Cb = 1.0.

Problem 1: Use AISC 360-16 Table C-A-7.1 to determine the effective length factor and determine the LRFD design compressive strength of a W12x50 column shown in the figure below.

Question: Use AISC 360-16, LRFD throughout 9. Considering only the limit state of bending about the major axis (x-axis), select the lightest weight wide flange of A992 steel to support a factored moment Mux of 175 kip*ft. Neglect the self-weight of the beam.

Question: Question 2 (25 points): According to the AISC 360-16 provisions, investigate the acceptability of HEB 450 section for column CD (all members are of S355 steel; F, = 355 MPa). The axial compressive load is 500 kN dead load (D) and 2000 kN live load (L), and bending moments are neglected. Use 1.2D + 1.6L load combination.

Question: In accordance with AISC 360-16, what is the strength reduction factor (Phi) associated with the limit state of tensile yielding? What is the strength reduction factor (phi) associated with the limit state of tensile rupture? Why is there a difference in these two values?

Calculate the equivalent moment factor for the following doubly symmetric simply supported beam following the CSA S16-19 standard. Do research and calculate the equivalent moment factor (which is known as lateral-torsional buckling modification factor, Cb, in AISC 360-16) based on American steel standard, AISC 360-16. Compare the results between these two steel standards.

Question: Find the design flexural strength of a W21X48 beam spanning over 30 ft with only its end points braced. Use the AISC 360-16 equations. Assume Fy = 50 ksi. W21x t 30- t

Question: b) An American design standard AISC 360−16 recommends that the deflection of a steel beam shall not exceed 1/360 of the span. As shown below, if the beam deflection is crudely assumed as a bilinear curve, the 1/360 limit approximately corresponds to the rotation angle of 1/180 (rad). Discuss whether the small deformation assumption is valid for the beams
