Abstract
This article first elaborates on the basic theory and core concepts of structural reinforcement design, emphasizing its important role in improving the safety and durability of building structures. Subsequently, the article conducted an in-depth analysis of the current structural status of old residential buildings, including their historical evolution, diagnostic methods for structural damage and diseases, and pointed out the urgency and importance of reinforcement design. In the section of structural reinforcement design methods, detailed discussions were conducted on aspects such as structural evaluation, strength and stiffness improvement design, seismic design, and reinforcement. Among them, structural evaluation is the foundation of reinforcement design, which helps designers comprehensively understand the current situation of building structures and provides scientific basis for subsequent reinforcement design. The design of enhancing strength and stiffness improves the load-bearing capacity and stability of the structure by increasing the size of structural components, changing the structural form, or using new materials. Seismic design and reinforcement are aimed at addressing the impact of natural disasters such as earthquakes on building structures, and corresponding measures are taken to improve the seismic performance of the structure. Finally, the application methods of structural reinforcement construction technology for old residential buildings were discussed. The setting and fixing of reinforcement components, the selection and application of materials, the application of prestressing technology, and the implementation of external reinforcement technology are all key links to ensure the quality and effectiveness of reinforcement construction. The application of these technologies not only improves the efficiency of reinforcement construction, but also ensures the safety and stability of the reinforced building structure.
