| 摘 要： | 对于复合材料箱形梁来说,假设应力沿梁宽度均匀分布会对强度分析造成较大误差,剪力滞效应属于不可忽视的因素。该文通过对0°/90°/0°/90°/0°]铺层的碳纤维复合材料层合板制成的薄壁箱形两跨连续梁进行静力加载试验,将试验结果与理论分析值进行了比较,研究分析了影响箱形梁的剪力滞效应。

| Abstract: | Speaking to the composite material box beam,the shear lag effect should belong to the inneglectable factor if it is supposed that the stress evenly distributing along the beam width will make the larger error for the strength analysis.Through the static loading test of two thin-wall box continuous beams fabricated of overlaying of carbon fiber composite material plywood,the article compares the experimental result and the theoretical analyzing value,and analyzes the shear lag effect influencing the box beam... |
