- Calculate the shear force and bending moment in each beam at sections 1-1, 2-2 and 3-3.arrow_forwardA timber beam is 120 mm wide and 200 mm deep and is used on a span of 4 metres. The simply supported beam carries a uniformly distributed load of 2.8 kN/m run over the entire length. Calculate the maximum bending stress induced.arrow_forwardA simply supported beam of hollow rectangular cross section is 100mm deep and 60mm wide with a wall thickness of 10mm. The beam has a span of 6m and carries a load as shown . Neglecting the weight of the beam draw a bending moment diagram and calculate the maximum bending moment. And determine the maximum bending stress in the material.arrow_forward
- Compute the initial deflection of the beam at midspan under service loads with the following specifications: f'c = 4000 psi, 36-inch height, depth of rebar assumed to be 3 inches less than the height, 16-inch width, 4 #9 bars (tension), Grade 60 rebar, 30' clear spans, service loads of: DL = 0.25k/ft, LL = 1.2k/ft. The DL does NOT include self-weight of the beam or of the precast concrete deck planks that have a weight of 60 PSF. The beam picks up a tributary width of 12 feet. Also, note that this beam is continuous and is the middle beam of 5 equal spans. Check the initial deflections against the ACI deflection requirements. Then calculate the long-term deflections and check those against the ACI requirements. For both situations, assume that finish materials will be attached to the beam. Last: Instead of performing a structural analysis to determine the maximum deflection in the beam, conservatively figure that the maximum deflection will be 60% of what it would have been for a…arrow_forwardA simply supported 3 m long beam with a point load of 5 kN and a cross section of 50 mm * 80 mm is applied in the middle of the beam. Calculate the maximum transverse shear stress acting on the beam cross section.arrow_forwardDerive the formula for the bending stress of a beam with a rectangular cross section and triangular cross secrion.
