With the continuous development of cities, the number of old buildings is increasing. The reinforcement, renovation, and durability improvement of these buildings have become important topics in the current architectural field. This article delves into the reinforcement and renovation techniques for old buildings, including commonly used methods such as section enlargement reinforcement and steel-encased reinforcement. It analyzes the advantages, disadvantages, and scope of application of each technique. The factors affecting the durability of old buildings, such as environmental erosion and material aging, are also discussed. Through the rational application of reinforcement and renovation techniques and the implementation of targeted measures, the safety and durability of old buildings can be effectively improved, providing strong support for the sustainable development of cities and realizing the reuse value of old buildings.
