摘要
针对目前加固效果评价方法不太理想的状况,结合拱桥加固处治的二次受力特性,在依据总体挠度变化率的刚度评价方法基础上,提出了基于动力特性频率的拱桥加固效果评价方法。根据工程实例,利用MIDAS/CIVIL软件经过计算分析,进一步证实了基于动力特性频率评价方法的全面、计算工作量少、反应较敏感的优点,表明该方法能为除拱桥之外其它桥型的加固效果进行评价。
Due to imperfect method for reinforcement effect evaluation,strengthening effect evaluation for arch bridge was proposed according to the second load for the strengthening treatment of arch bridge,rigidity evaluation of overall deflection change rate and characteristics of dynamic frequency.According to specific projects,advantages of the evaluation method based on the frequency of dynamic characteristics were confirmed through MIDAS/CIVIL for calculation;it was demonstrated that this method could provide useful guidances for strengthening effect evaluation of other bridges.
