Congestion of reinforcement at a beam-column joint is a practical problem because

  • A.congestion increases the ductility of the connection
  • B.the bars reduce the strength of the concrete they are cast into
  • C.concrete cannot be placed and compacted properly around the bars
  • D.the joint needs no reinforcement and the bars are superfluous

Answer: C

A honeycombed joint has neither the strength nor the bond the design assumed, and the defect is hidden once the formwork comes off. Larger columns, fewer larger bars and careful detailing of bar layout are the usual ways round it.
