| 摘 要： | 通过12根加载角度不同的矩形截面框架柱在斜向水平荷载作用下试验,研究其双向受剪承载力相关关系和利用新旧《混凝土结构设计规范》(征求意见稿GB50010-200x和GB50010-2002),计算矩形截面框架柱双向受剪承载力的差异.结果表明,矩形截面钢筋混凝土框架柱双向受剪承载力符合椭圆相关性,利用GB50010-200x和GB50010-2002标准均可安全计算其双向受剪承载力,GB50010-2002标准的安全性略高于GB50010-200x标准,而且随着加载角度增加,新旧标准计算矩形截面框架柱双向受剪承载力的差异性有增大趋势,加载角度为45°时达到极大值,而后又随着加载角度的增大而降低.

| Abstract: | To investigate the correlation property between bilateral shear strength of rectangular frame column and the divergence of bilateral shear strength measured on new and old standards described in Code for Design of Concrete Structures GB50010-200x and GB50010-2002,a total of 12 rectangular frame columns subjected to oblique horizontal load with various loading angle were experimented.The results indicated that the relationship between bilateral shear strength of rectangular frame column can be described as a... |
