【摘要】：我国建筑结构设计统一采用设计基准期为50年来计算建筑结构的可靠度,在设计基准期50年过后,并不意味着该结构寿命的结束。而是结构的可靠度开始下降,为了保证该结构的可靠度,就需要对其进行必要的检测、鉴定及加固,以确保该建筑的安全及使用性能。对房屋的结构检测、鉴定及加固技术的研究,已成为一个备受关注的课题,具有较好的社会意义和经济效益。本文综合运用混凝土结构检测技术、混凝土结构加固设计及施工技术,对已产生较大损伤的某单位混凝土框架结构办公楼进行检测鉴定,分析研究各种加固方法的基本原理及适用范围,提出了合理的加固设计方案,首先,对发生损伤最严重的地下室顶板进行顶升,然后,对混凝土压碎、纵向钢筋受压屈曲的地下室柱端,采取恢复混凝土及钢筋后,再将整个柱加大截面加固方法；对产生裂缝的梁和板,采用粘钢和粘贴碳纤维相结合的加固方法。加固后效果良好,避免了较大的经济损失和安全隐患,又减小了社会的负面影响。
[Abstract]:The construction structure design of our country is unified with the design reference period for 50 years to calculate the reliability of the building structure. After 50 years of the design reference period, it does not mean the end of the structure life. But the reliability of the structure begins to decline. In order to ensure the reliability of the structure, it needs to be tested, identified and strengthened to ensure that the structure is reliable. The safety and performance of the building. The research on the structure detection, identification and reinforcement technology of the building has become a subject of great concern. It has good social significance and economic benefit.
In this paper, the design and construction technology of concrete structure, concrete structure reinforcement design and construction technology are used to test and identify the office building of a certain unit concrete frame structure which has caused great damage. The basic principle and application range of various reinforcement methods are analyzed and studied. The roof of the serious basement is jacking up, and then the concrete and the reinforced concrete and steel bars are crushed by the concrete and the steel bar, and then the whole column is reinforced after the concrete and the steel bar is restored; the beams and plates that produce the cracks are reinforced by the combination of the bonded steel and the adhesive carbon fiber. The reinforcement effect is good and avoids the comparison. Great economic losses and hidden dangers also reduce the negative impact of the society.
