| 摘 要： | 通过试验和ANSYS有限元数值模拟的方法研究了简支深肋组合扁梁的受力性能和受力过程中截面的应力、应变的分布规律,并通过材料力学理论和结合试验量测结果对梁截面的抗弯刚度及简支梁的平均刚度进行了分析。验证了简支深肋组合扁梁的弹性受力分析中采用的平截面假定的合理性,并提出了简支梁深肋组合扁梁抗弯刚度的计算方法。

| Abstract: | The bending behavior of the simply-supported composite slim beam with deep deck and the stress and strain distributions in sections were investigated by test and FEM numerical simulation using software ANSYS.The results indicated that the sections of the beam remain flat during the elastic deformation stage,so the classical beam theory in material mechanics was used to analyze the bending stiffness of beam sections and the average stiffness of the simply-supported beam in combination with the measuring data in tests.A formula to calculate the bending stiffness of the simply-supported composite slim beam with deep deck was proposed. |
