Abstract:
The experimental results from tests of four beam-column subassemblies constructed with high-strength concrete (f'c = 9500 psi [65 MPa]) are presented and the results compared with the response of a specimen constructed with ordinary-strength concrete. The specimens were subjected to inelastic cyclic loading. The primary variable for the study was the shear stress in the joint. Modification of the maximum allowable joint shear stress is recommended. It is concluded that when properly designed, high-strength concrete subassemblies will exhibit sufficient ductility.
