PROBLEM 7.2: To comply with architectural requirements, a column in a non-sway frame is of T-section as shown. The longitudinal reinforcement consists of 6 20mmo bars in the flange and 3 - 28mmø bars in the web with 10mmø lateral ties. Neglect the concrete area displaced by the steel. f = 27.5 MPa and fy = 415 MPa. Clear concrete cover is 40mm. a. b. C. Determine the location of the geometric centroid of the section measured from the x and y-axes. Ans: x= 248.529 mm, y = 0 Determine the location of the plastic centroid of the section measured from the x and y- axes. For all bars use fs = fy. Ans: x= 262.751 mm, y = 0 Determine the bending moment Mu induced by a factored load Pu= 2800 kN acting along the x-axis at 400mm from y-axis. Ans: M₁ = 384.297 kNm 250mm 350mm 150mm 300mm 150mm 6-20mmØ bars in compression 3-28mmØ bars in tension 10mm0 lateral ties

What is the role of Internet of Things (IoT) in construction safety?
Goodday Maam or sir.. can you atleast help me on what should we do? or what would be our product please?? I just need an idea maam/sir please.. thank you in advanceSubmit a technical report highlighting engineering products (inventions, product, equipment) on your field grounded by chemistry principles. Civil engineering students will choose products applied or used or to be used in the civil engineering industry, same with Computer engineering students choosing products used in the computer engineering industry. So about computer engineering
