基于结构检测与抗震评估的高层住宅建筑安全性能研究

Study on Safety Performance of High-Rise Residential Buildings Based on Structural Inspection and Seismic Evaluation

摘要: 以某高层住宅建筑为研究对象，基于房屋安全性鉴定与抗震鉴定，采用现场检测、材料性能测试、结构承载力验算及抗震措施评估等方法，对该建筑的结构安全现状进行综合评价。结果表明：建筑主体结构安全性等级为B_su级，略低于A_su级标准，不显著影响整体承载，结构承载力和抗震能力满足现行规范要求；采用多种检测方法相互验证的方案，有效提高检测的可靠性。针对检测中发现的构件裂缝、钢筋锈蚀等问题，提出了修复建议与使用维护措施，为类似高层住宅建筑的安全评估与维护提供了有益的参考与借鉴。

Abstract: Taking a high-rise residential building as the research object, based on the assessment of building safety and seismic resistance, a comprehensive evaluation of the structural safety status of the building was conducted using methods such as on-site inspection, material performance testing, structural bearing capacity verification, and seismic measures evaluation. The results show that the safety level of the main structure of the building is B_su level, slightly lower than the A_su level standard, and does not significantly affect the overall bearing capacity. The structural bearing capacity and seismic resistance meet the requirements of current regulations; The scheme of using multiple detection methods for mutual verification effectively improves the reliability of detection. Suggestions for repair and maintenance measures have been proposed to address issues such as component cracks and steel corrosion discovered during inspections, providing valuable reference and guidance for safety assessment and maintenance of high-rise residential buildings.
