SITUATION 2. To prevent excessive deflection of a 9-m fixed beam, a pipe column is added at midspan. The beam is to carry a uniform load of w = 21.5 kN/m. Take flexural rigidity = 33.33 x 10^12 N-mm^2.
4. Calculate the reaction of the pipe column if it is rigid. (Ans. 96.75 kN)
5. Calculate the reaction of the pipe column is the pipe column is 2.4 m long, made of steel, has an outer diameter of 250 mm and thickness of 3 mm. (Ans. 92.56 kN)
6. If the pipe column yields by 2.4 mm, calculate the uniform load w that the beam is carrying. (Ans. 108.15 kN/m)
