钢筋混凝土结构加固方法分析

Analysis on strengthening methods of reinforced concrete structures

累积损伤、材料老化以及各种灾害将导致混凝土结构抗力衰减,安全性降低。本文基于钢筋混凝土结构加固原理,对钢筋混凝土结构加固方法进行了研究,从加固技术特点、适用范围及构造要求3个方面,详细分析了增大截面加固法、粘贴纤维复合材料加固法及粘贴钢板加固法。结果表明:粘贴纤维复合材料加固法加固效果高强高效,施工最便捷,宜优先选用。

Cumulative damage,material aging and various disasters will lead to the attenuation of the resistance of concrete structure and the reduction of its safety.Based on the strengthening principle of reinforced concrete structures,the strengthening methods of reinforced concrete structures is researched,and the strengthening methods of increasing section,bonding fiber composite materials and bonding steel plates are analyzed in detail from three aspects:technical strengthening characteristics,application scope and structural requirements.The results show that the bonded fiber composite material has high and efficient strengthening effect,and its construction is the most convenient,so it should be preferred.
