Sensitivity Parameter Analysis of Bearing Capacity and Ductility of Reinforced Concrete Columns with Z-Shaped Cross-Section
In order to select sensitivity parameter of bearing capacity and ductility, the orthogonal design method was used to research reinforced concrete (RC) columns with Z-shaped cross-section under compression and bending, by the nonlinear analysis computer program of RC columns with irregularly-shaped cross-section. The seven parameters and four levels of orthogonal design were researched, for example ratio of limb length to limb thickness, ratio of axial compression, loading angle, concrete strength, long reinforce ratio, stirrup diameter and stirrup spacing. The results indicated that the best sensitivity factor of bearing capacity was ratio of limb length to limb thickness, next were loading angle and long reinforce ratio; the best sensitivity factor of ductility was ratio of axial compression, next were stirrup diameter and stirrup spacing. These would afford references for the design of RC columns with Z-shaped cross-section.
