Abstract: A one-fourth scale outrigger beam-column frame with as-built details was tested to assess its performance under reversed cyclic loading and to develop a retrofit procedure suitable for moderate seismic regions. The ductility ...

Abstract: Two series of full-scale specimens were constructed and tested under pure axial load to investigate the effectiveness of confinement provided by headed bars. One series consisted of columns and the other series represented ...

Abstract: This study investigates the effect of the volume fraction of steel fibers on the axial load response of 200 MPa ultrahigh-strength concrete (UHSC) columns. Behavioral aspects investigated include strength, ductility, and ...

Abstract: Twelve ultrahigh-strength concrete (UHSC) columns confined by rectangular hoops and crossties were constructed and tested under pure axial load. Primary variables of the investigation were the amount, spacing, and configuration ...
