Abstract

In the shear design of massive walls in nuclear power plants, the use of high-strength reinforcing bars need to be considered to satisfy the high-strength demand and to enhance the constructability and economy. Recently, the use of Grade 550 MPa shear rebars for shear and shear-friction design provisions of RC walls is being reviewed in ACI 349 committee. In the present study, RC walls with Grade 420 MPa, Grade 550 MPa, and higher were tested under cyclic lateral loading to investigate the effect of high-strength reinforcement on the shear strength and shear-friction strength. On the basis of the test results, design recommendations for current shear and shear-friction provisions were proposed.
