摘要(Abstract):

通过对8根十字形截面钢筋砼柱在轴向力及双向弯矩共同作用下的反复加载试验,研究此类柱的延性及滞回曲线的一般规律。在此基础上,采用全过程非线性分析方法,编制了相应的电算程序,对其延性性能做了进一步的理论分析。最后,提出了十字形截面钢筋砼双向压弯柱截面延性的计算公式,并对轴压比、箍筋间距等一系列构造要求提出了设计建议。
Based on the experimental study of 8 R. C. short columns with " +" shaped cross section subjected to axial compression and cyclically biaxial bending, this paper reveals the general regularity of ductility and hysteretic behavior of " +" shaped R. C. colunms under axial compression and biaxial bending. On the basis of above mentioned works, by using the nonlinear analysis method of complete response process, a special computer program is compiled. The theoretical analyses of deformation behavior for R. C. columns with " +" shaped cross section subjected to axial compression and biaxial bending are carried out. Finally, the calculation for mulas of curvature-ductility for " + "shaped cross section are given. Based on the present investigation, some designing suggestions relating to axial compression ratios as well as spacing of stirrups are proposed.
