Abstract: This is the second of two papers presenting the results of a research program aimed at studying the stress-strain response of confined concrete. A confinement model for spirally confined concrete has been developed and ...

Abstract: An analytical stress-strain model for concrete confined by spiral steel was developed. The model is based on the concrete–spiral steel interaction. The deformational behavior of concrete under axial and lateral compression ...

Abstract: Reversed cyclic loading tests of eight prestressed and two nonprestressed concrete exterior beam-column joint assemblies that failed inside the joint cores were conducted. The test results revealed no significant difference ...
