| Advanced R.C.C. Design-Question bank Posted: 01 Dec 2010 08:02 PM PST R.C.C Circular Water Tank. Q. 1) The R.C.C. overhead circular water tank has an internal diameter 7.5m and height of wall is 4.0 m. The base slab of tank is supported over its periphery by a circular ring beam. Using M20 concrete and Fe415 steel, design the roof slab, wall and base slab. Sketch reinforcement details. Assume freeboard of 0.3m. Q.2) The bottom circular ring beam of R.C.C. overhead water tank has mean diameter of 7.0m and supported over six columns which are symmetrically provided. Design the ring beam for following data :- i) size of each column – 450mm dia. ii) U.D.L. on circular beam – 250 KN/m (inclusive S.W.) iii) width of beam – 400mm iv) The standard coefficients are for support B.M. Β= 0.089, for mid span B.M. β’= 0.045 v) For maximum twisting moment β’’=0.009 at 12.75 Support. vi) Use M20 and Fe 415 steel. Q.3) The R.C.C. overhead circular water tank has an internal diameter 8.0m and height of wall is 4.5 m. The base slab of tank is supported over its periphery by a circular ring beam. Using M20 concrete and Fe415 steel, design the roof slab, wall and base slab. Sketch reinforcement details. Assume freeboard of 0.3m. Q.4) The bottom circular ring beam of R.C.c. overhead water tank has mean diameter of 7.5m and supported over six columns which are symmetrically provided. Design the ring beam for following data :- i) size of each column – 450mm dia. ii) U.D.L. on circular beam – 275 KN/m (inclusive S.W.) iii) width of beam – 425mm iv) The standard coefficients are for support B.M. Β= 0.089, for mid span B.M. β’= 0.045 v) For maximum twisting moment β’’=0.009 at 12.75 0Support. vi) Use M20 and Fe 415 steel. Q.5) The R.C.C. overhead circular water tank has an internal diameter 8.0m and height of wall is 4.5 m. The base slab of tank is supported over its periphery by a circular ring beam. Using M20 concrete and Fe415 steel, design the roof slab, wall and base slab. Sketch reinforcement details. Assume freeboard of 0.3m. |
