摘　　要：由于异形柱的截面形状与墙身一致,避免了结构柱在建筑平面中的外凸,增加了建筑可用面积,近年来在结构设计中应用日益广泛.运用自编的基于纤维模型柔度法非线性分析程序,对四榀平面框架进行了分析,并从骨架曲线和滞回曲线两个方面与试验结果进行了比较,表明骨架曲线计算与试验值吻合得很好,验证了基于纤维模型有限单元柔度法非线性分析程序适用于框架结构,而且对于含不规则截面的结构也适用.Because of identification of section of the column of special-shaped and wall, bulge of column out of wall was avoided. More useful area was gained. Design of the column special-shaped is adopted widely recently. Four plane frames were calculated by the program of finite element flexibility method based on fiber model in this paper. Envelop curves and hysteretic curves were compared with the test results. Envelop curves are almost the same. The results show that the program could be used to analyze frames and structures with anomalous section.
