Civil Engineering :: RCC Structures Design
- The self-weight of the footing, is
- If permissible working stresses in steel and concrete are respectively 1400 kg/cm² and 80 kg/cm² and modular ratio is 18, in a beam reinforced in tension side and of width 30 cm and having effective depth 46 cm, the lever arms of the section, is
- The pitch of the main bars in a simply supported slab, should not exceed its effective depth by
- Top bars are extended to the projecting parts of the combined footing of two columns L distance apart for a distance of
- For a ribbed slab
- Design of a two way slab simply supported on edges and having no provision to prevent the corners from lifting, is made by
- Cantilever retaining walls can safely be used for a height not more than
- If the bearing capacity of soil is 10 tonnes/cm² and the projection of plain concrete footing from walls, is a cm, the depth D of footing is
- For normal cases, stiffness of a simply supported beam is satisfied if the ratio of its span to its overall depth does not exceed
- If depth of slab is 10 cm, width of web 30 cm, depth of web 50 cm, centre to centre distance of beams 3 m, effective span of beams 6 m, the effective flange width of the beam, is
