【摘要】：通过建立力学模型,应用弹性力学中的半逆解法对水平荷载作用下钢板深梁应力与位移进行计算。推导出钢板深梁有关的应力分量与位移分量的解析计算公式。结果表明:非加劲钢板深梁计算所得结果与试验结果对比,能够满足精度要求。对于两侧加劲钢板深梁,随加劲肋与钢板的面积比的改变,钢板深梁应力分布也发生改变。当面积比为0时,所得解与非加劲钢板深梁解一致;随面积比增大时,钢板深梁正应力减小,最终近似为纯剪受力状态。所得解为构件设计和稳定性分析提供理论基础。
[Abstract]:By establishing a mechanical model, the stress and displacement of deep beam of steel plate under horizontal load are calculated by using the semi-inverse method in elastic mechanics. The analytical formulas of stress and displacement components for deep beam of steel plate are derived. The results show that the calculated results of deep beam of non-stiffened steel plate can meet the requirement of precision compared with the experimental results. For both sides of stiffened steel plate deep beam, the stress distribution of steel plate deep beam also changes with the change of the area ratio of stiffened rib to steel plate. When the area ratio is 0, the solution is consistent with that of non-stiffened steel plate deep beam, and with the increase of area ratio, the normal stress of the steel plate deep beam decreases, and the ultimate state of pure shear force is approximately. The results provide a theoretical basis for component design and stability analysis.
