随着城市化的发展,火灾对建筑物以及人的生命财产安全所造成的危害日益严重。因此,本文就型钢混凝土柱在火灾后的加固修复研究方面进行了论述,主要是围绕着预应力钢带加固法、外包角钢加固法、碳纤维布加固法等加固方法,重点论述了三种加固方法的加固方法与加固效果。通过对比三种加固方法可得:预应力钢带加固法、碳纤维布加固法主要提高的是SRC柱的延性,外包角钢加固法则主要提高的是SRC柱的强度;相比之下,外包角钢加固法对火灾后SRC柱承载能力的修复效果最好,甚至可以达到常温未受火之前的状态。
With the development of urbanization, the harm caused by fire to buildings and people’s lives and property is becoming more and more serious. Therefore, this paper discusses the reinforcement of steel reinforced concrete columns in the post-fire reinforcement research, mainly around the reinforcement of prestressed steel, angle steel reinforcement method, reinforcement methods such as carbon fiber cloth, focusing on the three reinforcement methods Reinforcement method and reinforcement effect. Compared with the three kinds of reinforcement methods, it can be obtained that the strength of the SRC column is mainly enhanced by the prestressed steel strip reinforcement method and the CFRP reinforcement method mainly for the ductility of the SRC column, while the outer corner steel reinforcement method mainly improves the strength of the SRC column. In contrast, Act on SRC post-fire column carrying capacity of the best repair, and even can be achieved at room temperature before the fire state.
