摘要 研究了钢结构或钢筋混凝土组合结构梁柱半刚性连接的计算模型和对框架变形及截面内力的实际影响 ,在非线性迭代过程中 ,采用改进弧长法控制 ,提高了计算精度和算法的收敛性。实际算例表明半刚性连接会使剪切变形和二阶效应的结果增大。 This paper deals with the calculating model of steel or steel-concrete frame with semi-rigid connection between beams and columns and the actual effect on the deformation and internal forces of sections in the non-linear iterative process,the accuracy is enhanced and the convergence is expedited.The result shows that semi-rigid connection can make enlargements of shear deformation and second-order analysis.The investigation of this paper provides standard and background materials for the code of design of steel structures with semi-rigid beam-to-column connection.
