Some Detailing Problems in Concrete Frame Structures

For some years, research has been carried out at the Cement and Concrete Association to study the relative structural merits of different reinforcement arrangements for certain common situations in reinforced concrete structures. This work was started partly because a few failures had occurred in practice and partly because there was a lack of basic data on how detailing affected strength. Early projects were therefore concerned with specific areas where problems had been experienced either in practice or in previous research projects and were aimed at determining the optimum steel arrangement purely in terms of strength. Topics covered at this stage included half-joints, flexural corners and compression splices in columns; the structural efficiencies of these were reported in a previous paper presented to this Institution'.
