Erratum: “Behavior of R/C Bridge Bent with Grade Beam Retrofit under Simulated Earthquake Loads” [Earthquake Spectra 20, 91–118 (2004)]

1) Page 109—After Equation (11) the following should be revised as follows (underlining shows corrected text): ‘‘where sx and sy5compressive stresses in the joint in the xand y-directions (0.95 MPa and 0.28 MPa, respectively), and txy5shear stresses in the joint (2.33 MPa). The principal tensile stress was st51.74 MPa or 0.30 Afc8, and the principal compressive stress was found as sc52.97 MPa or 0.09 fc8...In the present case the curvature ductility exceeds 7.0, so the capacity for principal tension is 0.29 Afc8 (MPa) which was exceeded by a factor of 1.03.’’
