Paper Title:
Study on the Bearing Capacity and Ductility of Steel Reinforced Concrete Cross-Shaped Columns
  Abstract

Compared with reinforced concrete shaped columns, bearing capacity and ductility of steel reinforced concrete shaped columns are significantly improved, so it is with theoretical significance and practical application of value to research. Based on the plain cross section presume, with material cross-section boundary calculation unit, 15 steel reinforced concrete cross-shaped columns(SRCCSC) have made nonlinear full-rang numerical analysis. It demonstrates that the most adverse curvature ductility load angle of SRCCRSC is 45°.Loading angle (), axial compression ratio (n), and the ratio of spacing and diameter of longitudinal reinforcements (s/d) are the principal factors in curvature ductility of SRCCSC subjected to biaxial eccentric compression. Under the most unfavorable loading angle, through a regression analysis of curvature ductility computer data of 150 cross-shaped columns with 8mm stirrups diameter and 150 columns with 10mm stirrups diameter, it can be obtained with the relationship betweenand axial compression ratio n,s/d, of SRCCSC subjected to biaxial eccentric compression.
