Braced cuts

The braced cut is a method of providing lateral support to the soil in foundation trenches, to prevent the trenches from deformation by the caving in of soil and resisting it from moving laterally. During shallow excavation in firm soil, generally, slopes are provided to resist the caving in of soil. During shallow excavation in soft soil and deep excavation, the chances of caving in of soil increase. Hence, it becomes necessary to make a provision to resist the deformation of trenches due to caving in of soil. The braced cut is the method used for such conditions. The excavation using braced cuts is a bit uneconomical as compared to the traditional open-cut excavation method but provides better safety than the cut excavation method.

If concrete with a compressive strength of 35 MPa is used for a circular column to support a factoredload of 5.75 MN, what diameter of column (mm) is required to withstand the factored load?
Determine the required spacing of #3 stirrups (Grade 40) along the length of a 5000 psi, 35-ft long concrete beam. The beamwidth is 15 inches and the height is 36 inches. Estimate that the bottom layer of reinforcement is centered at 3 ½ inches from the bottom of the beam. Assume that you should provide a maximum of 3 different spacings (and perhaps only 2) for the stirrups so as not to overcomplicate matters for the contractor. The service loading on the beam is 1 k/ft for the dead load (does NOT include self-weight) and the service live load is 2 k/ft. The beam is cast monolithically with the columns and is a single span. Include the effects of the shear maximum envelope. Show all checks for minimum and maximum allowable stirrup bar areas and spacings per ACI 318-19. Please DRAW and label the factored maximum shear envelope diagram across the length of the beam (with the φ factor included). Please DRAW an elevation view of the beam for one-half of the beam length to scale and…
