| 摘 要： | 纤维增强复合材料(FRP)管约束下的矩形截面混凝土短柱在轴向受压条件下,由于FRP管与混凝土间的黏结使得FRP管同时受到拉、压双向受力状态;核心混凝土由于FRP管的约束而受到3向应力作用.以Tsai-Wu屈服准则为基础,进行FRP管双向受力分析,利用双剪强度准则对核心混凝土进行3向受力分析,推导轴心受压条件下FRP管约束矩形截面混凝土短柱的受压强度计算方法,为极限承载力的计算提供一种有效的方法和参考.

| Abstract: | Abstract： Based on the Tsai Wu yield criterion, the stress analysis of fiber reinforced polymer (FRP) tubes was conducted. And the twin shear unified strength theory was used to analyze the stress of the core concrete under triaxial stress state. Besides, the strength calculation method to predict the ultimate stress under axial compression of short concrete columns with rectangular cross section confined by FRP tubes was deduced to provide an effective method and the reference for the calculation of the ultimate bearing capacity. |
