Describes a three-edge bearing test program on 39 specimens with welded wire fabric reinforcing. The work program was part of an investigation to develop a rational procedure for the design of precast reinforced concrete pipe. Many test specimens were instrumented with SR-4 electric strain gages. In addition to strain measurements, recorded test data included sequence of crack formation, load versus vertical and horizontal deflections; load at 0.01 -in. crack, ultimate strength, photographs of failure mode, and strength and stress-strain behavior of steel and concrete materials. A summary of test results from three other test programs is also included.
