Article Preview

In order to determine the strength and deformation characteristics of confined concrete under axial compression of cruciform columns, the test results have been obtained for reinforced concrete cruciform columns through axial compression experiment in the study. After analysis and research, the stress-strain curves of confined concrete have been established, the relational expression between the relatively increased value of the peak strain value of confined concrete in cruciform columns and the stirrup characteristic value was proposed, the descending section of the stress-strain curves of confined concrete was studied, and the variation relationship between the strain ductility coefficient of the confined concrete and the stirrup characteristic value was established. The study results will be provided as reference for the structural design and deformation calculation of cruciform columns.
