摘要
为改善腹板开洞RC梁的受力性能,利用Abaqus有限元分析软件,在低周反复荷载作用下,对26根腹板开洞RC梁进行不同洞口长度、洞口高度、洞口偏移、钢板厚度参数数值模拟分析。模拟分析结果表明,带肋钢板加固腹板开洞梁相比未加固试件有良好的受力性能、耗能能力,变形能力增强,刚度退化减缓。有限元数值模拟分析为合理确定带肋钢板加固开洞梁参数提供了理论依据。
In order to improve the mechanical behavior of RC beams with web openings,using Abaqus finite element analysis software,under the action of low cycle load,numerical simulation analysis was carried out on 26 RC beams with holes in webs with different length,height,deviation and thickness of steel plates. The results of simulation analysis show that the reinforced web beam with ribbed steel plate has better mechanical performance,energy dissipation capacity,deformation capacity and stiffness degradation than the unreinforced specimen. The finite element numerical simulation analysis provides a theoretical basis for reasonably determining the parameters of the reinforced perforated beams with ribbed steel plate.
