| 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.文中运用自编的基于纤维模型柔度法非线性分析程序,对3座底层抽柱的异形柱钢筋混凝土空间框架进行了程序分析,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空间框架,而且对于抽柱的不规则结构也适用.

| Abstract: | Because of the identification of sections of special-shaped columns and walls,bulge of column out of wall may be avoided,and more useful area may be created in buildings.Special-shaped columns are wilely adopted recently.Three spacial 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.The results showed that the program could be used to analyze spacial frames and anomalous stru... |
