Abstract:

?为建立组合结构桥梁使用的开孔板连接件抗剪刚度计算方法,以开孔板孔径、混凝土强度和弹性模量及孔中钢筋直径、强度和弹性模量等为变化参数,进行了60个模型试件的抗剪刚度试验;分析各试件剪力-相对滑移曲线的切线与割线的斜率比值变化,提出了以相对滑移0.2mm对应的割线斜率为开孔板连接件抗剪刚度的取值方法;采用弹性地基梁法分析了孔中混凝土及钢筋的抗剪机理,推导了开孔板连接件抗剪刚度的理论计算表达式;基于理论分析和123个模型试验提出了开孔板连接件抗剪刚度的计算式。研究结果表明:计算式反映了孔中混凝土、孔中钢筋及其对混凝土约束的作用,物理意义明确,可用于钢-混凝土组合结构考虑结合面开孔板连接件作用的计算分析。
