Text for problem 1: What is the reaction at B, and D? What is the shear and bending moment at distance @2m from B on the span BD? What is the maximum flexural stress of thr beam if its section has a depth of 400 mm and a width of 200 mm?
A 400mmx500mm beam carries a total factored load of 55kN/m uniformly distributed over its 7.30m span, in addition the beam will be subjected to a uniformly distributed torsion of 7.40 kN-m/m at factored loads. Closed stirrup steel (10mm) will be used to provide for flexural shear and torsion. Use a clear cover of 40mm and diameter of longitudinal bars to be 25mm. Assume fc’=28MPa, fy=420MPa and fyt=280MPa. A.) Determine the threshold torsion, kN-m. B.) Determine the calculated spacing of stirrups for torsion, mm? C.) Calculate the value of the longitudinal steel area required by torsion, mm2
Please answer this immediately. Thank you!
The beam shown below is subjected to a uniform live load, ωL = 1k/ft. In addition, the beam must resist a superimposed dead load, ωD.S = 0.8k/ft as well as its self-weight. The concrete strength is 6,000 psi and the steel is Grade 60. The beam is not in contact with the ground or exposed to weather (hint: cover). Calculate the nominal and design shear strengths of the beam section. Is the beam shear design adequate? If so, redesign the beam to make the design more economical. If not, redesign the beam for shear to ensure the design is adequate per ACI 318-19 standards. . The beam shown below is subjected to a uniform live load, ωL = 1k/ft.

M1AQ99. For a loaded propped beam in the figure below, design a singly reinforced beam (using the USD method and NSCP 2015) for the positive moment. Give the complete details of the design. The total depth of the beam must not exceed 600 mm to ensure acceptable floor-to-floor vertical clearance. f'c = 28 MPa and fy = 415.7 MPa. It carries a super- imposed dead load of 90 kN/m and a live load of 38.4 kN/m all applied over the entire length of the beam. Other load and beam properties are the following: L1 = 6.3 m, L2 = 2.1 m, I2 = 0.65 of I1. Use a minimum concrete cover of 60 mm. Optimize the design such that the minimum percent difference of the moment strength with the actual moment is 1% but to avoid overdesign it's max percent difference is 5%. Design the rectangular beam details to provide: width, total depth, effective depth, number and diameter of tension bars (for two layers, provide number of bars in the upper and lower layer and vertical clear spacing between the 2 layers),…
