| 摘 要： | 在实际的加固工程中,拉区粘钢梁的应用多且其研究相对深入,而压区粘钢梁的应用相对较少,有关压区粘钢梁设计计算方面的研究亦很少。开展压区粘钢梁承载力及刚度和挠度等计算方法的研究,具有工程实用价值。根据11根压区粘钢梁的实验数据,结合理论分析,对压区粘钢加固钢筋混凝土梁在正常使用极限状态下的短期刚度和挠度的计算方法进行了分析和研究,提出了压区粘钢加固钢筋混凝土梁短期刚度和挠度的计算方法。理论计算与试验结果对比表明,所提出的计算方法具有较高精度。

| Abstract: | In actual strengthening project,beams with bonding steel plate in tensile region is widely used,and study of them is more in-depth.But the appllcation of beams with bonding steel plate in compression zone is less,and study of them in design calculation is also less.So to study the calculational method of bearing capacity,rigidity and deflection of beams with bonding steel plate in compression zone has an important value in project.Based on the experimental data of 11 bonding steel plate beams and theoretical analysis,the short period rigidity and deflection of bonding steel plate in compression zone were analyzed for concrete beams under ultimate state of normal service.And a method to calculate the short period rigidity and deflection of beams with bonding steel plate in compression zone was deduced.The contrast of theoretical calculation and experimental results shows the method has a good precision. |
