摘　　要：为解决由于混凝土强度偏低造成影响结构整体安全的问题,通过对某剪力墙结构案例进行分析论述,介绍了剪力墙置换混凝土加固设计方法以及施工要点。案例根据现场调查及检测结果,分别对混凝土最低强度要求、轴压比、钢筋锚固等不同指标进行计算分析并采用置换混凝土的方法对结构进行加固设计,并根据施工阶段计算分析,采用免支撑置换的方式进行施工。在不改变建筑使用功能、结构性能的前提下保证了结构安全,可为同类工程提供参考。To address the issue of compromised structural safety caused by low concrete strength,this study analyzes a case of a shear wall structure and introduces a reinforcement design method involving concrete replacement,along with key construction considerations.Based on on-site investigations and test results,the case evaluates various parameters such as minimum concrete strength requirements,axial compression ratio,and rebar anchorage.A concrete replacement method was applied for structural reinforcement design,and a support-free replacement technique was used during the construction phase,as determined through calculation and analysis.This approach ensures structural safety without altering the building's functional use or structural performance,providing a valuable reference for similar projects.
