房屋结构安全鉴定中金属构件损伤评估方法研究与应用OA

To systematically enhance the accuracy and reliability of damage assessment for metal components in building structure safety appraisal,this paper takes steel columns after explosion shock as an example.By introducing the plastic damage mechanism and multi-level assessment methods,a comprehensive assessment scheme integrating visual inspection,non-destructive testing,and numerical simulation is proposed.It concludes that this scheme can achieve quantitative diagnosis and graded treatment of damages.The research results show that this comprehensive system significantly improves the accuracy of damage assessment and provides effective technical support for engineering safety appraisal and decision-making.
