桥梁抗弯加固效果动静载力学分析

文章结合某桥梁出现主梁横向裂缝,且边梁纵向多处开裂,桥梁结构严重破坏实例,经过力学分析及实验研究结果对其进行钢板、碳纤维加固处理,采用动静载力学分析方法及附加荷载技术研究了桥梁加固前后的位移、挠度、应变、频率等动静力学参数变化情况,对加固后桥梁特性作出完整评价,为桥梁加固效果分析提供依据。

The Dynamic and Static Mechanical Analysis on the Effect of Bending Reinforcement for Bridge

Taking one bridge that has transverse crack on the main beam,several longitudinal cracks on the side beam and the bridge structure has been severely damaged as an example,the Paper,through mechanical analysis and laboratory study,presents how to reinforce and treat the steel plate and carbon fiber.By means of dynamic and static mechanical analysis method and based on the character of reinforced bridge,it also studies the variation of dynamic and static mechanics parameters before and after bridge reinforcement,such as displacement,deflection,strain and frequency.By doing so,it will be able to have a comprehensive evaluation on the character of reinforced bridge,and thus provide reference for the analysis of reinforcement effect of bridge.
