Transverse compression strength of heavily reinforced concrete

The static and fatigue strength of 150 x 150 x 450 mm concrete prisms with heavy concentrations of reinforcement placed transverse to the direction of applied load is compared to the strength of plain concrete prisms. Of eight patterns tested, only one is found to have a detrimental effect on the crushing strength. Results of specimens subjected to repeated loads are similar to those loaded monotonically. Confining reinforcement parallel to the axis compression should be placed outside such transverse reinforcement where this problem is encountered in practice.
