摘要
由于结构功能变化,为确保结构可以继续安全使用,需要对结构进行加固改造,以恢复或者提高其承载力。针对某混凝土框架结构加固改造实例,在对原结构进行分析鉴定的基础上,采用粘贴纤维复合材料加固法、外包钢加固技术、植筋增大截面法对框架柱、梁、板进行加固补强。在施工过程中,不断完善加固方案和对实施过程进行优化,取得了预期的加固效果,旨在为同类工程积累经验。
Since the structural function changes,the structure needs to be reinforced and reconstructed to ensure its continuing safe use,to restore and increase its carrying capacity.Aiming at a reinforcement example of a concrete frame structure,based on the analysis and checking calculation of the original structure,the frame column,beam and plate are reinforced using such measures as reinforcement method with adhesive fiber composite material,encased steel reinforcement technology and planting bar to increase cross-section.In the course of construction,the reinforcement scheme is continuously improved and the implementation process is optimized,the expected reinforcement effect is obtained,and experience is accumulated for similar projects.
