Question

For the beam assigned to you solve a) Find the reactions, Draw the shear diagram, Draw the moment diagram b) Calculate the moment of Inertia of the cross-section about its x-x neutral axis using the parallel axis theorem and compare this to the Qnesteel value. Do the two values agree? c) Determine the maximum tensile bending stress and indicate its location in the section d) Calculate the maximum shearing stresses in the cross-section and draw a profile ofthese shearing stresses showingtheir magnitudes at the critical points and Analyse the tophalf of the Universal Section allocatedto you, so it becomes a T-Section, and use the 1st moment of area method to find the Centroid of the T- Setion relative to axis x-x y.dA Loading diagram 30kN Uniform Load 8kN/m 3 metres 2 metres 3 metres 8 metres Use 200 UB 18.2 for beam -picture with details is attached onesteel U3 Universal Beams UB Table 13 Universal Beams-Dimensions and Propertles .m-19 112 0.5 Abouty-axis 99 91 3.5-TB 1.6-6,0 13 69-67 61 55-6A 61 5.0-63 58 5.0 45 6,0 5.0 45 6,0 5.0 Aboutx-axis 비m 220 220 220-200 200- Flange mmm-iss 195 199 105 105 24-194 iza 193 99-90 90 90-75万 Constant Constant 190 190 esignation Depth ot ' | mm 02 scr 600 ,,1岰EST Thickness Radius Between 201 201 201 202 198 79仍仍| 195 150 惢400 199 350 300 104 198 250 U3 UB HAS SP 7m Ed April 2014
