Civil Engineering :: RCC Structures Design
- Columns may be made of plain concrete if their unsupported lengths do not exceed their least lateral dimension
- The number of treads in a flight is equal to
- An R.C.C. column of 30 cm diameter is reinforced with 6 bars 12 mm φ placed symmetrically along the circumference. If it carries a load of 40,000 kg axially, the stress is
- If d and n are the effective depth and depth of the neutral axis respectively of a singly reinforced beam, the lever arm of the beam, is
- The allowable tensile stress in mild steel stirrups, reinforced cement concrete, is
- In a singly reinforced beam, the effective depth is measured from its compression edge to
- The steel generally used in R.C.C. work, is
- The advantage of reinforced concrete, is due to
- The spacing of transverse reinforcement of column is decided by the following consideration.
- ‘P’ is the pre-stressed force applied to the tendon of a rectangular pre-stressed beam whose area of cross section is ‘A’ and sectional modulus is ‘Z’. The maximum stress ‘f’ in the beam, subjected to a maximum bending moment ‘M’, is
