摘　　要：基于考虑材料非线性和几何非线性耦合梁柱单元模型,采用截面高斯积分法,它不同于以往的截面分块和条带积分法,编制了钢筋混凝土构件非线性全过程分析程序;通过钢筋混凝土构件非线性全过程数值分析,研究影响钢筋混凝土压弯柱侧向位移的诸多因素(轴压比、加荷角、截面尺寸、配筋率、混凝土强度、剪跨比等)对柱侧向位移的影响情况,提出设计参考建议,为工程设计提供理论依据。Based on the element model considering material nonlinearity and geometry nonlinearity, the program of nonlinear analysis of reinforced concrete（RC） members is developed by using section Gauss integration method which is different from past section integration methods such as grid-method and strip-method. By tracing full-path analysis of RC columns under one- or bi-directional bending and compression, some factors influencing lateral displacement are researched, for example, axial compression ratio, load angle, section dimension, reinforce ratio, concrete strength, shear span ratio et al. Some advice is suggested. This offers theoretical reference information for engineering design.
