某校宿舍楼建筑结构安全性鉴定
|
摘要
以某校宿舍楼的安全鉴定为工程背景,通过贯入法及回弹法等技术手段,对建筑结构的砖砌体抗压强度、梁柱混凝土强度、结构侧向位移进行精细化检测,对建筑结构布置进行精细化检查与分析,并基于检测数据对该建筑结构的安全性进行评级。检测结果表明:该宿舍楼结构安全性鉴定等级评定为Dsu级,即安全性严重不符合鉴定标准的要求,严重影响整体承载,建议立即采取加固措施,并加强后续使用的监控量测工作。
Taking the safety appraisal of a school dormitory building as the engineering background,the compressive strength of brick masonry,the strength of beam-column concrete,the lateral displacement of the structure and the layout of the building structure are measured by penetration method and rebound method,and the safety of the building structure is graded based on the test data. The test results show that the structural safety appraisal grade of the dormitory is Dsu grade,which means that the safety does not meet the requirements of appraisal standards seriously,and affect the overall bearing capacity seriously. We suggested that reinforcement measures should be taken immediately,and the monitoring and measurement of the follow-up use should be strengthened.
