Abstract

The reinforced concrete (RC) column under horizontal load generally fails by bending or shear force. The shear fracture should be avoided in structural design because of its brittle behavior. However, the mechanism of shear fracture is not enough clear. In this paper, in order to investigate the effect of confinement by hoop on the shear deformation behavior of RC column, the simulation of the confined concrete under horizontal load was carried out by using a visco-elasto-plastic suspension element method (VEPSEM) which can dynamically simulate the fracture behavior of concrete with a non-continuum model. As the results, it is shown that the effect of hoops on the shear deformation behavior of confined concrete and the change from the bending fracture to the shear fracture by increasing axial stress can be expressed qualitatively by this analytical method.
