- Q.20 The main reinforcement in RC slab consists of 10 mm diameter bars at 100 mm c/c spacing. When 10 mm bars are replaced by 12 mm diameter bars then spacing would be1. What is the spacing of the torsional and shear web reinforcements? 2. What is the governing additional longitudinal reinforcements for torsion?1. Caused by what is the shear force? 2. The shear force is resisted by what reinforcement? 3. In which area does the shearing force usually occur in the beam? 4. What are the functions of stirrup reinforcement? 5. What conditions must be met if the stirrups are used to resist shear forces?
- Beam Shear Design Problem Reinforced Concrete DesignDetermine 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…What is the Split-tension test? How it is different from the Flexure Strength Test?
