Abstract: In order to study the mechanical properties of eccentric compression columns of high ductile concrete (HDC), the eccentric compression tests of 6 HDC specimens and 2 RC specimens were carried out. The failure mode, bearing capacity and deformability of the HDC column are studied. The experimental results show that replacing concrete with HDC can obviously mitigate the brittle failure of small eccentric columns and improve the deformation capacity of members with small eccentricity and compression failure. Compared with the RC large eccentric columns, the HDC large eccentric compression columns show better crack control ability, and the cracks of tension zone are uniformly distributed and tiny. With the increasing of eccentricity, the bearing capacity of the HDC eccentric compression members is reduced and the deformation capacity is improved. The mechanical analysis of the normal section shows that the bounding relative height of compression zone of the HDC eccentric compression member is higher than that of the RC members and is more beneficial to the mechanical performance of high strength steel bar. Considering the HDC tensile effect, the bearing capacity of the HDC eccentric compression member is in good agreement with the test results. The results of this paper provide experimental support and theoretical basis for the design of HDC eccentric compression members.
